Python for Beginners - Learn Python
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 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 program, So you can see here is a function called square which
is just a simple function that takes one parameter which is called a number, and it returns the
square of that number. Okay now let's say we wanted to call this function inside our for loop so to
do that we would type square(12.99) inside our for loop and after that hit enter so. In this case the
code would run and it declare and use variables in python.
