__doc__ of current function?

[Trevor Taylor]

Hi,

I thought it would be simple but couldn't figure it out, nor find it
addressed already:

I can do:

def validatePassword(p):
'do something'
print validatePassword.__doc__

.... can I write a general docOfCurrentFunction() function so that I
can rewrite it:

def validatePassword(p):
'do something'
print docOfCurrentFunction()

Thanks,

Trevor

'do something'
print docOfCurrentFunction()

def docOfCurrentFunction():
import sys
func_name = sys._getframe(1).f_code.co_name
return eval(func_name + '.__doc__')

But I hope that a more intelligent way exists than using 'eval' :)

Maybe

import sys
def caller(): .... f = sys._getframe(1)
.... return f.f_globals[f.f_code.co_name]
.... def demo(): .... "Demo docstring"
.... print caller().__doc__
.... demo() Demo docstring

Or can that fail in some cases?

Hi.
Yes, it fails for methods:

import sys
def caller(): .... f = sys._getframe(1)
.... return f.f_globals[f.f_code.co_name]
.... class C: .... def m(self):
.... "mmmmmmmmmm"
.... print caller().__doc__
.... c = C()
c.m() Traceback (most recent call last):
File "<interactive input>", line 1, in ?
File "<interactive input>", line 4, in m
File "<interactive input>", line 3, in caller
KeyError: 'm'
