how do you write a function in python

def functionName():
    # What to make the function do

# Basic Example
def addNum(num1, num2):
    print(num1 + num2)

# To call this function
addNum(2, 4)

# Output: 6

python create function

name = input("What's your name?")
def greet(name):
	print("Hi", name+"! Nice to meet you.")

greet(name)

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!

how to make a def in python

# declare a function
def function_name(param) :
  # content inside a function

function_name(param) # calling function

how do you write a function in python

#A function is a collection of code, which performs a specific task. 

def say_hi(name, age): #This defines the function you can also add 
                       #variables in the parentheses
  print("Hello " +  name + ", you are " + str(age)) 

say_hi("Justin", 36) #This calls the function and executes the code
say_hi("Jhon", 38)   #Inside the parentheses you can state the name          
say_hi("Jason" , 40) #and age that you want to run

#when you are naming a function, name the function with all lowercase.
#If you have a short two word name of your function it is not necessary
#to use a underscore symbol ( _ ), however if you want to there is no 
#problem.

functions in python

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'

  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!"""

You need to install js2py or requests-html packages to run the JavaScript program from Python

//example :
//javaScript function : squareofNum()

squareofNum = "function f(x) {return x*x;}"

result = js2py.eval_js(squareofNum)

print(result(5))

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!

python functions

'''
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)
