definition in 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: 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 3: 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 4: 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 5: * meaning in python

The * in python represents "The rest".
Meaning it will take the remaining arguments that are left over in your 
code and fit inside the variable OR you can use it as your primary 
variable to store as many arguments that you want.
After doing this it it will convert them into a list.

Example 6: what does * mean in python in functions

>>> numbers = [2, 1, 3, 4, 7]
>>> more_numbers = [*numbers, 11, 18]
>>> print(*more_numbers, sep=', ')
2, 1, 3, 4, 7, 11, 18
