defs python code example

Example 1: how to make a function in python

def test_function(argument1,argument2,argument3) :
  # Do something with the code, and the arguments.
  print(argument1)
  print(argument2)
  print(argument3)
  
# Calling the function.

test_function('Hello','World','!')

# Output
'''
Hello
World
!
'''

Example 2: python functions

# Python Functions
def a_function(): #def FUNCTIONNAMEHERE(): Function content
  print("Hello World!")
  return 0
def answerValid(prompt, correct_answers, invalid): # Functions can also have parameters, or variables that can be used only in tha function
  while True:
    user = input(prompt)
    if user in correct_answers:
      break 
      return user # Example Function
   	else:
      print(invalid)

a_function() # To call a function; Prints 'Hello World!'
# But if this is done:
function_called = a_function() # function_called would contain a 0, because the function returns 0
answer = answerValid("What is 8 * 8?", [64], "Invalid Option")
print(answer) # Prints 64, because that is the only possible answer
