Python

Python is a wicked cool [sic] interpreted scripting language that a lot of people start their programming journeys with. It has an easy to read, dynamically typed syntax that appeals to beginners and people who suffer from great sloth.

Basic Examples

The basics of Python are to start a file with the path of the interpreter. If you have written code in BASH, Perl or Ruby you will recognize the opening line.

   #!/usr/bin/env python

To run your python application, you have two methods. If you are using a UNIX based operating system you can use the `chmod` command to make the file executable, or pass it as an argument to the python interpreter.

   $ chmod +x my_file.py && ./my_file.py

Alternatively:

   $ python my_file.py

Printing

Printing to the screen is always the most basic introduction to a programming language.

   #!/usr/bin/python
   
   print("Hello World!")

Variables

Variables are a way of representing data with human-readable names.

   #!/usr/bin/python
   
   my_variable = "Hello "
   print(my_variable + "World!")

As you can see, we used the variable in the print() function and concatinated it with the rest of the string "Wolrd!".

Arithmetic

Python, like all languages, can do math as well.

   #!/usr/bin/python
   
   num = 5
   print(num + 6)

The above program will display the sum of 5 and 6 (11, you pleb). You can use any of the following operators:

• + (addition)
• - (subtraction)
• / (division)
• * (multiplication)
