Re: [capi-sig] Solved Strange Python behaviour after C-Function

Sorry for bothering you,

I just made a stupid error in C, mixing up variable names, so one of the returned lists had the wrong content and wrong length... strange python behaviour anyway...

Hi all,

thanks for the numerous replies to my previous questions.

Everything in C works fine so far, but there is a very strange behaviour in python after visiting the C-Function.

The return value of my C-Function is a list of floats. I can print that list, I can do:

a=0 while a

works fine, but if try to do

for element in list: print element

It does that as well, but as soon as the end of the list is reached, I do get an IndexError: list assignment index is out of range. Surprisingly I do get that as well with any list, where I try to use the for loop after using the C-function. So if I use an arbitrary list like

ll=[1,2,3] for l in ll: print l

I do get the same error, and I don't before calling the C-function...

Does that sound familiar to anybody? Is that caused by one of the decref/incref things? Kind regards Philipp
