1、Python 装饰器获取类名

def print_name(*args):
    def _print_name(fn):
        def wrapper(*args, **kwargs):
            print('{}.{}'.format(fn.__module__, fn.__qualname__))
            return fn(*args, **kwargs)
        return wrapper
    return _print_name
class A():
    @print_name()
    def a():
        print('Hi from A.a')
@print_name()
def b():
    print('Hi from b')
A.a()
b()

Output:
main.A.a
Hi from A.a
main.b
Hi from b
