using a string to call a method

[darktemp]

Is it possible to use a string to call a method?
Say I got a string x = txt (which is a known file extension to my program) and I have a method called txt(value). When x changes to doc, is there a way to make my program call to doc(value)? I tried x(value) (which is a nonexistent method) and I get a string object not callable.

I hope I am clear enough about it. Thanks :].

Hi

You want the eval command.

Good luck!

Wow that was really quick and nicely made. Thanks :].

Glenton,

Although eval will work, getattr() is a much better solution.

>>> class Foo:
...     def __init__(self):
...         pass
...     def test(self):
...         print "It worked!"
...         
>>> a = Foo()
>>> getattr(a, "test")()
It worked!
>>>

Oh, I misunderstood the questions! Nice one.
