function in pytho code example

Example 1: python functions

def myFunction(say): #you can add variables to the function
  print(say)

myFunction("Hello")

age = input("How old are you?")

myFunction("You are {} years old!".format(age))

#this is what you get:

Hello
How old are you?
>>11 #lol my real age actually
You are 11 years old!

Example 2: how to define function in python

def example():			#This defines it
  print("Example.")		#This is the defined commands

example()				#And this is the commands being run

Example 3: python functions

# first we have to write 'def'
# then our function name followed by ()
# and a ':' abd defining  block of code

def multiply():     # naming convention could be same as variable for functions
    product = 10.5 * 4
    return product


product = multiply()
print(product)

Example 4: 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

Example 5: functions python examples

def multiply(a, b):
