Python Programming: A Concise Introduction

1803 calificaciones

The goal of the course is to introduce students to Python Version 3.x programming using hands on instruction. It will show how to install Python and use the Spyder IDE (Integrated Development Environment) for writing and debugging programs. The approach will be to present an example followed by a small exercise where the learner tries something similar to solidify a concept. At the end of each module there will be an exercise where the student is required to write simple programs and submit them for grading. It is intended for students with little or no programming background, although students with such a background should be able to move forward at their preferred pace. The course is four modules long and is designed to be completed in four weeks.

De la lección

Tuples, Data Dictionaries, Text and CSV Files

So far, we have one collection data type, the list. In this module we take up two more: the tuple and the data dictionary. After that we introduce reading and writing text files and give some illustrative examples. Finally, we take up reading and writing Comma Separated Value (CSV) files.

This video shows how to run Python programs on Windows 10 PC without using Spyder.

The remaining videos use Spyder to do the same thing,

using a feature Spyder,

which may be phased out by the time you get to this point.

That feature, I'll discuss at the end of this video.

This is the program that we're going to run, print("Hello World!"),

just a simple program,

doesn't have to be complicated to illustrate running programs.

Here it is in my directory.

Now, to open a command prompt,

I'm going to get in here to Cortana, search field,

then I'll type CMD,

then I'll choose command prompt,

and there it opens.

Then I will type, cd space documents/pythoncoursera/lesson3.

That's where that pattern is on my machine.

Yours may be at a different place.

Now type, python hello, and run it.

That's all there's to.

Let me give you a couple of other things that you might need, and might not know.

If you need to know whether the program is saying you can type dir.

Now, in this case,

there's so many files there, I can't find it.

So, I type dir and hello,

and I use this wildcard asterisk

to show me everything that begins with "hello", and ends in.py.

And there are two things out there.

So, I can see that the file is there.

Also in getting there,

you may need to move upper directory.

Say, if we are from lesson three to the directory above it,

it may need to move down a directory,

and you can do that.

Now, let me show you another way to do this.

First, I'm going to shrink this to kind of get it over either way,

then I'm opening up this directory.

This is Windows Explorer,

and it shows "hello,

right there!", in this directory.

Now, let's go run hello again.

Click the end of the Cortana search field,

and type CMD, run the command prompt.

And I'm going to move this parallel to that,

so that they're both visible easily.

Up here, notice that this tells you where I am,

but it's not in a path for me.

But if I click here in the white,

it changes and highlights,

and I can type, Control+C and copy it.

Then I go over here, and type cd space,

Control+V to paste it there.

That keeps you from having to do all of this typing

and avoid errors and typos or somethings like that.

So, now we're at the right directory.

We can type python hello.py, and it runs again.

So, you just click here, paste here.

Now, let's look at a third way of doing this.

Back here in Spyder,

we've got the directory up there, "Hello" is here.

I'm going to use that to get there.

Click down here, CMD,

bring this up, put it up here parallel.

Now, I'm going to click over here, and highlight that,

press Control+C to copy it over the Window,

cd space, Control+V, put on the python hello.py,

and then run it.

Now, earlier in the course,

we wrote our programs here,

and then we ran them in the IPython console down here.

What we're going to do when we have whole words,

we're going to write them here,

and run them over here.

So, we've got a different pane that's outside of

Spyder running the program, but it works no different.

Let me type the change to this program.

Print("Goodbye"),

save that change over here,

paste that there, bring it in,

run it, do you see a change?

Now, let's look ahead at what's going to be coming up.

I'm going to be writing programs like this.

In my case, I have a copy of Spyder,

then in the tools menu,

there is an open command prompt, watch down here.

When I click on open command prompt,

I got a command prompt just like this one. Colors are reversed.

It's just like this one. I can type python hello.py,

and run this program.
