Extention Module/ list of chars-> string

[Tuvas]

I am currently writing an extention module that needs to recieve a list
of characters that might vary in size from 0 to 8. This is written as a
list of characters rather than a string because it's easier to
manipulate. However, when I pass this list of characters into the
extention module, it keeps giving errors. Is there a way to do one of
the following?

A. Change a list of chars to a single string or
B. Read a list of chars in an extention module

Thanks!

Either is possible, but I recommend to do A:

data = ''.join(data)

Then pass the modified data to the extension module.

A. Change a list of chars to a single string or
that's easier to do at the python side of things (see martin's reply), but
if you'd rather do
B. Read a list of chars in an extention module

you might find the code on this page somewhat useful:

(use PyString_Check, PyString_Size and PyString_AsStri ng to process
the sequence items. see the C API reference for details)

Thanks for the help, I actually ended up writing my own simple
charlist2string function, I realized it was only about 4 lines of code,
but, appreciate the help!
