what does def do in python code example

Example 1: 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 2: python def

# You can make a function by using the [def] keyword
def foo():
	print("Hello")

# You can run it by calling it as such
foo()

def add(numA, numB):
  print(numA+numB)
  # or 
  return numA+numB

num = add(1, 5)
print(num)

Example 3: how to define a function in python

def function_name():
  pass

Example 4: python funtion

def nameOfFunction(something):
  	return something

Example 5: how to define a function in python

variable = "Hello, world!" # variable = string("Hello, world!")

#A simply function :

def Functiontest(): #define a function
  print("Hello, world!")
  print(variable)
 
#Function with components :

def Functiontestwithcomponent(arg1, arg2): # Define a function with two arguments, arg1 and arg2.
  if arg1 == True: # Arguments can have any name, like variables.
    print(arg2)

#Call a function :
Functiontest() #Start Function.

#Call a function with two components :

Functiontestwithcomponent(True, "Hello, function!") #Start Function and precise two arguments :

Example 6: 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!"""
