[SOLVED] Python 2 to Python 3

grail · 03-04-2010, 01:52 AM

Hopefully a quickie (but I can't seem to find anything so far).

I have a function definition in a Python 2.x script which take a
tuple as one of its arguments, but 2to3 has no answers nor any of my searching on how to represent the same in Python 3.x

Code:

def blah(self, (string1, string2)):

Any help greatly appreciated

Cheers
Grail

    string1, string2 = string_tuple

Hi Dan

Please let me know if your solution still works in the following scenario?

Code:

def blah(self, (string1, string2)):
    return blah2('help', (string1, string2)) 

def blah2(self, name, stringx=None):
    ...

Yes, it will. Passing a tuple to a function is unaffected. You just can't declare function arguments like that anymore. Here's why.
