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
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-programs inside your python
