I'm learning Python!

Python is case-sensitive.

REPL is started by running python or python3. To exit out of the REPL, run CTRL-D.

To run a program thru the python interpreter run


python3 hello.py

Assign variables just by naming them in snake-case like this


first_name = "Frank"
print(first_name, "is learning Python!")

Ask input from the user by using


first_name = input("What is your first name? ")
print(first_name, "is learning Python!")

Naming things is hard. Here are Pythons's naming conventions.

Functions are created with the def keyword and the {} are replaced with a :

Indention is important in Python


def yell(text): 
  text = text.upper()
  number_of_characters = len(text)
  result = text + "!" * (number_of_characters // 2) 
  print(result)

Python uses try except instead of try catch. To raise an excemption use raise
