实现您自己的装饰器

# mydecorators.py

def resolve_function(func):
    #in case annotated func is an staticmethod
    if isinstance(func,staticmethod):
        return func.__func__
    return func

def print_my_name(func):
    def function_caller(*args,**kwargs):
        _func = resolve_function(func)
        print("my name is: %s" %_func.__name__)
        return _func(*args,**kwargs)
    return function_caller

然后使用它

# foo.py

from mydecorators import *

@print_my_name
def bar():
    #do something else
#in terminal: my name is: bar

我把这个实用工具放在附近:

import inspect
myself = lambda: inspect.stack()[1][3]

用法:

myself()

你可以使用装饰器:

def my_function(name=None):
    return name

def get_function_name(function):
    return function(name=function.__name__)

>>> get_function_name(my_function)
'my_function'

str(str(inspect.currentframe())).split(' ')[-1][:-1]

我用自己的方法在多重继承场景中安全地调用super(我把所有代码都放在这里)

def safe_super(_class, _inst):
    """safe super call"""
    try:
        return getattr(super(_class, _inst), _inst.__fname__)
    except:
        return (lambda *x,**kx: None)


def with_name(function):
    def wrap(self, *args, **kwargs):
        self.__fname__ = function.__name__
        return function(self, *args, **kwargs)
return wrap

示例用法:

class A(object):

    def __init__():
        super(A, self).__init__()

    @with_name
    def test(self):
        print 'called from A\n'
        safe_super(A, self)()

class B(object):

    def __init__():
        super(B, self).__init__()

    @with_name
    def test(self):
        print 'called from B\n'
        safe_super(B, self)()

class C(A, B):

    def __init__():
        super(C, self).__init__()

    @with_name
    def test(self):
        print 'called from C\n'
        safe_super(C, self)()

测试:

a = C()
a.test()

输出:

called from C
called from A
called from B

在每个@with_name修饰的方法中，您可以访问self。__fname__作为当前函数名。

我找到了一个包装器，它将写入函数名

from functools import wraps

def tmp_wrap(func):
    @wraps(func)
    def tmp(*args, **kwargs):
        print func.__name__
        return func(*args, **kwargs)
    return tmp

@tmp_wrap
def my_funky_name():
    print "STUB"

my_funky_name()

这将打印

my_funky_name 存根
