Re: [Pythoncard-users] List components

[Azam, N. <na...@wr...>]

Thank you Steven - that worked perfectly!  That was exactly the solution for my problem.

Thanks also for the explanation of why I was seeing that behavior.

Regards,
Naweed.

I'm not an expert on Pythoncard, but given the description of the error, I would try passing the list of movie titles directly rather than a single string. E.g. instead of:

# clips is a list of movie titles
self.components.List1.items = str(clips)  

I would use this:

self.components.List1.items = clips  


This assumes that each movie title is a string.

Calling str() on a list of strings gives you a single string:

py> clips = ['Warm Bodies', 'Gone With The Wind', 'Alien']
py> str(clips)
"['Warm Bodies', 'Gone With The Wind', 'Alien']"


and then iterating over that string gives you individual characters, including those from the list itself:

py> for element in str(clips):
...     print element
... 
[
'
W
a
r
m
[... snip long output ...]


Does this help?
