define function in function python code example

Example 1: python function

def name():#name of the def(function);
  print("Hallo, World!")#Output is Hallo, World!;
  
name()#Name of the def, the programm will jump to the def;

#output:
#Hallo, World!

Example 2: 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 3: python define a function within a function

def print_msg(msg): # This is the outer enclosing function
    
    def printer():# This is the nested function
        print(msg)

    return printer  # this got changed

# Now let's try calling this function.
# Output: Hello
another = print_msg("Hello")
another()

Example 4: nested functions in python

def print_msg(msg):
    # This is the outer enclosing function

    def printer():
        # This is the nested function
        print(msg)

    return printer  # returns the nested function


# Now let's try calling this function.
# Output: Hello
another = print_msg("Hello")
another()
