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 would run for each item in the list called list and then it would go
inside the parentheses and it would assign the item inside those
parentheses to the variable called item. So in this case, the code would
print out apple Banana cherry pineapple, so you can see how this works if
you wanted to change what was inside those parentheses. You could do
that by simply typing different values for parenthesis. So in this case, I
typed apple Banana cherry pineapple. So now you understand how to use a
for loop alright. Now last but not least let's talk about functions. Functions
are blocks of code that you can use in your python programs to simplify
your code or to make it more powerful. You can think of functions as mini-
