python def function code example

Example 1: how to write a function in python

# We use the def keyword to write a function in python
# Format: def function_name():
# For example:
def Bark():
  print("Bark! Bark!")

# If we want to run the function
Bark()

Example 2: 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!
