Hello Emile,
Why don't you use the func name directly?
print show2.__doc__
I mean it's a constant in the sense that it is know at design time, right? And
you need it anyway, as shown by the fact that it becomes a string literal in
the your version.
It's not like if you would _not_ know it ;-) Fortunately, funcs (and methods
and classes and modules -- but not other object AFAIK) know their own
(birth)name:
def docString(obj):
name = obj.__name__
return globals()[name].__doc__
Should work for the above listed object types. Anyway, other types have no
docstring...
