Python program to illustrate closures code

Copy the below python program and execute it with the help of python compiler.

import logging 
logging.basicConfig(filename='example.log', level=logging.INFO) 
  
  
def logger(func): 
    def log_func(*args): 
        logging.info( 
            'Running "{}" with arguments {}'.format(func.__name__, args)) 
        print(func(*args)) 
    # Necessary for closure to work (returning WITHOUT parenthesis) 
    return log_func               
  
def add(x, y): 
    return x+y 
  
def sub(x, y): 
    return x-y 
  
add_logger = logger(add) 
sub_logger = logger(sub) 
  
add_logger(3, 3) 
add_logger(4, 5) 
  
sub_logger(10, 5) 
sub_logger(20, 10)

import logging

logging.basicConfig(filename='example.log', level=logging.INFO)

def logger(func):

def log_func(*args):

logging.info(

'Running "{}" with arguments {}'.format(func.__name__, args))

print(func(*args))

# Necessary for closure to work (returning WITHOUT parenthesis)

return log_func

def add(x, y):

return x+y

def sub(x, y):

return x-y

add_logger = logger(add)

sub_logger = logger(sub)

add_logger(3, 3)

add_logger(4, 5)

sub_logger(10, 5)

sub_logger(20, 10)

Output:
