Can somebody explain decorators for me pliz in python

Answer 1

Decorators are wrappers around functions, methods, and classes. Typically they add some functionality to the wrapped code but they can also be used to simply modify parameters or do some logging. Here's a simple example:

import time

def time_call(func):
def _wrapper(*args, **kwargs):
current_time = time.time()
func(*args, **kwargs)
elapsed_time = time.time() - current_time

print('Elapsed time: {}'.format(elapsed_time))

@time_call
def my_func(sec):
time.sleep(sec)

my_func(2)
# prints 'Elapsed time: 2000'

This is a simple example and there's way more you can do. This is a very powerful feature when used right.
