funciton python 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: 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 3: functions in python

#Function Tutoral:
def hello():
  print("hello")
"""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): #This time, there is two inputs for the function to prossess. 
  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!"""

Example 4: python functions

#Functions
def string():
  print('This is a function')
  
  print(string())
