Opposite of repr() (kind of)

[Guillermo]

Hi there,

How can I turn a string into a callable object/function?

I have a = 'len', and I want to do: if callable(eval(a)): print
"callable", but that doesn't quite work the way I want.

Regards,

Guillermo

Depends on what's in your string.

I have a = 'len', and I want to do: if callable(eval(a)): print
"callable", but that doesn't quite work the way I want.

Works here:
Python 2.5.1 (r251:54863, May 2 2007, 16:56:35)
[GCC 4.1.2 (Ubuntu 4.1.2-0ubuntu4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.

What version of Python are you using? I just tried
"callable(eval('len'))" on Python 2.5.1 and got True, and eval('len')
returns <built-in function len>.

This must be the dumbest question ever...

Solved.
