Example 1: python functions
def myFunction(say):
print(say)
myFunction("Hello")
age = input("How old are you?")
myFunction("You are {} years old!".format(age))
Hello
How old are you?
>>11
You are 11 years old!

"""To make a function, it needs def then nameOfFunction() and a : to
make the function work, you don't need a closing tag, as long as there is
tabbed section."""
def add(a, b):
c = a + b
return c
"""What the function above does is you input 2 numbers, and then it returns
#The Value c, Calling it is as simple as add(5, 1)
#What return does, is it almost makes a varible. So you can do:
#70 + add(10, 20) and it will return with: 100. This is because it will
go 70 + 30, as the function returned 30 because the inputs were 10 and 20."""
"""Functions can be called by code, as long as the function has already
been defined. Hope this helped you in your python journey!"""
