def function in python

OK, basically def function() is a block where you will have one task that you can repeat all over again in the code to make it look short and clean

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

python functions

def function():
  print('This is a basic function')
  
function()
// Returns 'This is a basic function'

def add(numA, numB):
  print(numA+numB)
  
add(1,2)
// Returns 3

def define(value):
  return value

example = define('Lorem ipsum')
print(example)
// Returns 'Lorem ipsum'

#Function Tutoral:

"""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."""

been defined. Hope this helped you in your python journey!"""

How to define a function in python?

def main():
#this will define your function, which you can use in the program
#or you can use it in other programs too, which ill show later
#also you have to call your function once atleast
	userinput = input("String: ")
    #ask the user for input, which is being stored in userinput
    if len(userinput) < 5:
    	print("it is longer")
    else: 
    	print("it is shorter")
main()
#this will call the function
'''
to use your function in other programs, you can just do the following
from (the name of the program you want to import the function from) import (function name)
done!

'''
Functions are very useful in python because you can use them instead
of repeating code in your program which makes your code messy.
'''

# This is how you create a function
def functionName():
  print('Hello World!')
  
functionName() # prints out 'Hello World!'
functionName() # prints out 'Hello World!' again

# Functions can have attributes which you insert into the function
def add(a, b):
  print(a + b)
  
add(2, 4) # prints out '6'
add(11, 35) # prints out '46'

# Finally, functions can return values which you can save as variables
def addFive(value):
  return value + 5

myVar = addFive(3) # myVar becomes equal to 8 (3 + 5)
print(myVar) # prints out myVar

'''
Keep in mind that scope comes into play in your functions. If you
create a variable in a function, it won't be saved outside the
function.
'''
def createVar():
	myVar = 5
    
createVar()
print(myVar) # returns error (unless you defined myVar outside function)
