This Python tutorial covers everything you need to know to start programming in Python,
from downloading the latest version of Python to learning about variables and data types. It
also provides an exercise for the reader to practice their skills.
Iphone or iPad you need to install a couple of other things first so you go to the App Store
and search for Pycharm. Then in the App Store click on the install button. Now. Once
Pycharm is installed, you can open it up by clicking on this icon. Here in your downloads
folder. You should also have a.py file. So let's open that up now. The first thing you 're going
to do is create a new project so let's do that by clicking on this green plus sign here in your
project explorer window and type in Python. This is the name of your project. Now let's
choose a location for your project so we're going to choose a folder on our computer called
projects and then click on the create Button Now let's change some settings inside of
Pycharm. So first thing you 're going to. To want to do is change the language of your project
to Python, So inside of pycharm. Go to File > Settings > Project Settings and in the
Languages section change Python to the language of your project. Now next thing you 're
going to want to do is set up your project folder so inside of pycharm go to File > Settings >
Project Structure and in the Project Folder section click on the Browse button and then
select the folder where you want your project files to live so now Your project is set up and
ready to go all right let's start writing some code. We're going to start with the simplest code
possible and that's a hello world program. In Python. A Hello world program is simply a
program that prints out hello world so let's open up our.py file and enter this code here. Here
import sys [UNK] world!") all right so we've imported the Sys module and then we've printed
out [UNK] world!" now Let's save our file by clicking on this green button here in your editor
window and call it Hello.py now let's run our program by clicking on this green run button
here inside of pycharm and you'll see that our program has printed out [UNK] world!" all right
that's our first simple code block in Python now Let's take a look at some more code blocks
in Python. First thing we'll want to do is create a variable, so let's open up our hello.py file
again and enter this code def [UNK] [UNK] world!") all right so we've defined a function
called say —hello() and inside of say —hello() we're going to print out [UNK] world!" now
let's save our file once again say we want to declare a variable called price. We would type
price and then after we type the name of the variable. We would put a colon and then the
value of that variable. So in this case, the value of this variable will be 12.99. So we can use
this variable anywhere inside our Python code now let's say we want to print the value of this
variable. We can do that by simply writing print price and then after that we would put a
period and then the value of the variable. So in this case the code would print out 12.99
alright. Now let 's say we wanted to change the value of this variable. We can do that by
simply typing new value for price and then after that we would type a colon and then the new
value of the variable. So in this case the code would print out 13.00 alright. Now let's say we
wanted to delete this variable. We can do that by simply typing delete price and then after
that we would type a period and then hit enter so In this case, the code would delete the
variable called price Alright. Now let's talk about lists. Let's say we have a list of items and
we want to display. each item in turn on our application window so to do that we need to use
a for loop so to declare a for loop. We would type for item in list, and then after that we would
type parenthesis, then the list item and then after that hit enter so In this case, the code
