How to define a decorator as method inside class in Python?
class myclass:
def __init__(self):
self.cnt = 0
def counter(self, function):
"""
this method counts the number of runtime of a function
"""
def wrapper(**args):
function(self, **args)
self.cnt += 1
print('Counter inside wrapper: ', self.cnt)
return wrapper
global counter_object
counter_object = myclass()
@counter_object.counter
def somefunc(self):
print("Somefunc called")
somefunc()
print(counter_object.cnt)
somefunc()
print(counter_object.cnt)
somefunc()
print(counter_object.cnt)
Output
Somefunc called Counter inside wrapper: 1 1 Somefunc called Counter inside wrapper: 2 2 Somefunc called Counter inside wrapper: 3 3
