Question

I try to add a pause after each execution of method, there is a way to do it automatically ?
Actually i’ve something like this :

import time
def test (arg):
    print arg
    time.sleep(0.1)
class Foo (Object):
   def __init__ (self, a, b):
       self.a = a
       self.b = b
       time.sleep(0.1)
   def printer (self, arg):
       print arg
       time.sleep(0.1)

Here is basically the same thing as @Fedor Gogolev’s solution,
except that this uses a class decorator instead of a metaclass.

import time
import inspect
import functools

def sleep(f):
    @functools.wraps(f)    
    def wrapper(*args, **kwargs):
        result = f(*args, **kwargs)
        time.sleep(0.1)
        return result
    return wrapper

def sleeper(cls):
    for name, method in inspect.getmembers(cls, inspect.ismethod):
        setattr(cls, name, sleep(method))
    return cls

@sleeper
class Foo(object):
   def __init__(self, a, b):
       self.a = a
       self.b = b
   def printer(self, arg):
       print arg


f = Foo(1,2)
f.printer('hi')
