Acerca del Curso

This course will introduce the learner to the basics of the python programming environment, including fundamental python programming techniques such as lambdas, reading and manipulating csv files, and the numpy library. The course will introduce data manipulation and cleaning techniques using the popular python pandas data science library and introduce the abstraction of the Series and DataFrame as the central data structures for data analysis, along with tutorials on how to use functions such as groupby, merge, and pivot tables effectively. By the end of this course, students will be able to take tabular data, clean it, manipulate it, and run basic inferential statistical analyses. This course should be taken before any of the other Applied Data Science with Python courses: Applied Plotting, Charting & Data Representation in Python, Applied Machine Learning in Python, Applied Text Mining in Python, Applied Social Network Analysis in Python....

The course had helped in understanding the concepts of NumPy and pandas. The assignments were so helpful to apply these concepts which provide an in-depth understanding of the Numpy as well as pandans

Wow, this was amazing. Learned a lot (mostly thanks to stack overflow) but the course also opened my eyes to all the possibilities available out there and I feel like i'm only scratching the surface!

The assignments are at a perfect introductory, yet not too trivial level.

However, I think the way the assignments are graded is very restrictive (i.e. the auto-grader expects very specific outputs with properties which are not essential to the solution required) and a lot of the student's time is wasted on rewriting the solution to accomodate this.

The "statistics" part of the course is unnecessary, as the only way in which it is relevant is one line of code in the fourth assignment. People who want to know what running a t-test means should be referred to Wikipedia.

Overall I had a great experience and I will do more courses on Coursera.

Personally, I find that the course is good. As it's name, the course teaches how to use Python in many basic Data science task.

I really appreciate the assignments, they cover well the introduced concepts.

However, the only negative point (for which I do not give the course 5 stars) is the speaking speed of speakers. I bet that there are not many students whose IQ is over 140 to understand the videos without pausing several times. I mean, the instructor should focus on the ability of listeners, there are so many times I even could not read what are being appeared on the screen while the instructor are keep speaking and speaking.

Really enjoyed the pace and realistic assignments. The skills I have learned would surely help me apply these techniques in the real world. The various discussions and articles though optional were excellent to give a thorough understanding. I would only point out that althogh the assignments were challenging and pose realistic problems, the automatic grader seemed to require the correct answers in too narrowly defined format which was often never clear from the instructions. Either the instructions should be made clearer or else the auto-grader should be 'smarter' explaining the actual reasons why something could be wrong.

Caution: This course is not beginner friendly

Warning: It will take longer then other courses to complete

the course if considered with the quality of assignment is good, but the lectures are very limited in coverage, This course requires exhaustive self study(which is not bad but in itself) but as a beginner you require more hand holding. some more lectures needed to be added to bridge the gap between assignment and lectures. The person with very limited time will struggle to complete the course on time. As for myself, i enjoyed the course but at time it was frustrating to the extend that i considered giving up on course.

Take this course for the challenging assignments. The well designed problems will require you to research and implement multiple Python features after visiting StackOverflow, reading documentation, exploring blogs etc.

I have taken away one star because the assignments also happen to be the only compelling reason to take this course. The video lectures, in my opinion, lacked both breadth and depth. There is a lot that you will 'kind of' understand, but very few topics that you will feel entirely confident about -- this is specially true for the last week where the instructor simply mentions several topics of statistics.

This course is mostly great. The automatic grading software usually provided helpful output, and when it didn't there were discussion threads with staff-posted answers that unblocked me, so I was never stuck. The assignments were great because they are generally real-world scenarios. There was a slight misalignment between the week 2 teachings and assignment which required some reading ahead and using StackOverflow, but otherwise the assignments aligned well with their weeks' teachings. The videos are easy to understand. I feel super comfortable with python, pandas, and Jupyter notebooks after taking this course.

The Videos were usually engaging, although the pacing was often too fast, and the video did not always match the words spoken, this was very distracting. The exercises and readings were excellent as they focused on big picture issues and the ethics of data science, which kept the course interesting as data science and coding can tend to be quite dry. The assignments were my favourite part as they were stimulating and often challenging. They really forced you to go back to the course content, and to the pandas documentation to figure things out. All in all a really enjoyable course, which I learnt a lot out of.

It is a really great course that forces you to rely on your ability to teach yourself, but has a great discussion forum that all students should be on to get the full understanding. I would like more feedback from the autograder and I would appreciate a bit more of a warning about the time estimate per week. Definitely 8-10 hours a week just in assignments. This is mostly due to the fact that the autograder can get you stuck, also make sure to use pandorable code because if you don't most likely your answer won't be correct. Overall learned a ton and can't wait to start the next course in this specialization!

To course content creators:

Thank you for working on keeping the course materials updated. While this is really important, it is really frustrating that a course is upgraded and you are forced to switch mid way through. I'm at the end of week 3 and as a new mom I have very limited time to work on my course work. For full time working learners/single parents/learners with several other commitments, the flexibility offered is of most importance. It's inexcusable to ask learners to complete a course in limited time when everyone signed up and paid for a course that you can take your time to complete.

I think the structure of the lessons are highly relevant for data sciecne and taught well. So for Syllabus content I think you are doing veryy well

Cons: Nearly all the problems I encountered were related to the autograder not being helpful! There could be better error handling/debugging i.e. instead of just saying the answer is wrong, explain why and the aswer that is expected. For example, I spent DAYS on the final question (run ttest)of the last assignment. I had the right answer all along except the autograder was expecting the type to be numpy float 64, whereas my answer was just a float!

What I like this course:

Assignment! Geat assignments. Challenging and learnt a lot.

What I do not like this course:

instruction videos: way too shallow, and no real examples. I understand pandas and numpy are both very comprehensive libraries and it is impossible to cover every details. However, if the instructor could teach a real case study,(like similar cases in assignments), learners could have better understading going into the assignments.

Finally, teacing staff are great, very helpful.

I learned a lot from this course, not from the instructors, but from assignments and teaching staff.

I can see a couple of problems in this course. How to access and change elements in a data frame (especially the use of loc and iloc) is not explained very well and I believe there is an error in the slides. The second thing is that I have found more powerful methods in pandas documentation, for example assign() or nlargest() and nsmallest(). This is not really a problem if one of the "hidden" purposes is to push students to actively search the docs for what they would like to do.

Work load for the assignments is just fine in my opinion, not too little, not too much.

Overall I am satisfied.

I felt that there was very little hand-holding in this course. I think there was good and bad from that. On the one hand, I think it could have been more helpful if the lecture content more directly correlated to the assignment questions. However, I definitely think that learning to utilize the internet (stack overflow etc.) is an integral part to coding in any language in today's landscape as well. So there is something to be said for that for sure. Overall, I think I learned a lot of valuable skills in the course and I'm looking forward to continuing the others in the specialization.

It is a very nice course, providing you are able to pour a LOT of individual efforts into it, especially into the assignments. The knowledge required to finish the course is far beyond what they taught. I spent 70% of my time in the course on Stackoverflow or Google, or asking my friends. However, I admitted I gained huge amount of knowledge and experiences, as well as "individual research skills" and confidence, from this course. I would recommend going through this course in a much shorter period of time than recommended (like in a week), during your vacation or week off.

Solid introduction to using Python for basic data science applications. By the end of the course I feel confident that I know how to go about cleaning data and doing some basic analysis on it. The practical programming assignments are great, you can really dig your teeth into them without them being so challenging that it scares you off. Expect it to take you longer to complete the assignments than the official estimated time.

What's also great is that all the code from the lectures is posted so you can easily play with it to be able to follow along with the lectures.

I didn't utilize the discussion pages until the third week, but they are extremely helpful. The pseudo code that was sometimes given in those discussions was also helpful for learning the material because it revealed programming solutions that I was unaware of given my inexperience with the python language. My only real issue is that I wasn't expecting the self-learning for the end of week assignments, but it wasn't that bad. The in-video problems were nice, I would like to see more small, non-graded assignments to help practice the language and get a feeling for it.

This is a really great course. It's super informative, the video lectures are more engaging than those of any other online class I've taken, and I have learned so so much. However, I started this course as more or less a complete beginner. If that's you, then be prepared to spend a ton of time and energy on the homework (around 6 hours per assignment). I fortunately had a friend who helped me out a lot, but if you're a complete beginner, short on time, and don't have access to someone who can help you, I'd recommend finding another course or working up to this one.

CONs: I did find some of the ungraded peer evaluations could use a little refinement. I've shared this feedback with the team though and I doubt it will get in the way of anyone else's learning.

PROs: Found the forum useful and between that and stackoverflow, getting the hang of Python for Data Science shouldn't be any trouble with those coming from an analyst or programming background. The ethics discussions and articles presented were good foundations for folks starting out in a field where communication of risks and biases is critical before acting on results.

This course is accurately advertised as requiring intermediate programming experience. It focusses on some of the basic python tools that are used in data science like pandas, specifically dataframes. For a python newbie like me, some of the assignments were quite challenging as they required significant additional reading and search. I would have appreciated if all of the concepts required to solve the assignments were introduced in the same week, so my additional reading and search would have been more targeted. Very little stats if any is required or taught.

Was a great overview of the Pandas and Numpy frameworks.I loved the course as it gives a quick overview to every aspect of pandas framework.But, what I absolutely hated was that the instructors just introduce you to every aspect and just do it themselves without much of an explanation, specially after week 2 ends.So, we need a lot of self studying which is super overwhelming to those of us who are just being introduced to data science in Python.Self-studying is a key aspect, but still a bit of more explanation in each video would have made the course 5-star.

I really like the lectures. They are fast paced, full of useful information. I also like the design and intentions of the assignments. They really help enhance the learning. I love the required reading too. It really expands your vision from a course to a much bigger world.

My gripe is mostly on the lack of attention to details for the assignment questions. There is a lot of ambiguity there. Forums and tips helped, but I would rather they spec out the questions in the first place. I hate to guess what the auto-grader want.

All in all, it's a very good course!

Loved the lectures and structure. Great course. The assignments were very educational, but I was a bit frustrated with the autograding at times. It felt like, what was preventing me from advancing had nothing to do with the actual course material, but the technical set-up instead. I don't know if it's possible, but having the auto-grader tell you what went wrong (which criteria your submission didn't live up to) would be a huge help and help students like me avoid too much frustration. Just a thought. Still a great course - keep up the good work :)

I found this course very useful and interesting. Assignments are very helpful to test your skills and how one can apply the content learned during lectures in actual problems. There is a lot of functionality and details in the Pandas library but, this course is designed very well to enable the students to get a good understanding of Pandas. Although, I faced some problems regarding the assignment grader. Moreover, the course videos end abruptly and it gets difficult to understand what the Professor was explaining towards the end of the lecture.

Com certeza o curso melhorou o meu conhecimento em python. Antes mesmo de terminá-lo já aplicava os conhecimentos no meu trabalho. Contudo, terminei trabalhando muito mais tempo nas provas do que o tempo estipulado pela equipe de instrutores. Cheguei a pensar que estava fazendo tudo errado, mas vi nos fóruns que outros também tiveram a mesma dificuldade. Estou muito satisfeito, não quero provas mais fáceis, apenas uma noção mais adequada do tempo que será gasto (levando em conta que estrangeiros podem demorar mais para entender o enunciado).

The videos were little fast paced. The explanation were good. It would be better if more detailed explanation on pandas has been given. Some more functions of pandas must be given because in assignment part the questions were little tricky and the question of that type has not discussed. You have to learn more from other resources. However overall course was good, it gives a good explanation on how to use python to manipulate data in table and many more. Before opting this course the individual should have a good grasp on basics of python.
