How to get a function name as a string?

Question

In Python, how do I get a function name as a string, without calling the function?

def my_function():
    pass

print get_function_name_as_string(my_function         


        

Answer 1

I like using a function decorator. I added a class, which also times the function time. Assume gLog is a standard python logger:

class EnterExitLog():
    def __init__(self, funcName):
        self.funcName = funcName

    def __enter__(self):
        gLog.debug('Started: %s' % self.funcName)
        self.init_time = datetime.datetime.now()
        return self

    def __exit__(self, type, value, tb):
        gLog.debug('Finished: %s in: %s seconds' % (self.funcName, datetime.datetime.now() - self.init_time))

def func_timer_decorator(func):
    def func_wrapper(*args, **kwargs):
        with EnterExitLog(func.__name__):
            return func(*args, **kwargs)

    return func_wrapper

so now all you have to do with your function is decorate it and voila

@func_timer_decorator
def my_func():
