- debug your extension from python first, then embed it
- don't call PyFinalize()

How can I solve it?
Providing exception text will be helpful.

Run your script as:
python -u script.py
for unbuffered output.

Works for me. (Win XP SP2, Py 2.4, only have c and d drives)

True
os.path.exists('e:\\')

Hello,
Please advise on multi-threaded list *append*:

print aList

If you can afford to keep the whole file in memory, than:
lines = open(..).readlines()
print lines[::-1]
Otherwise you can use seek() to random-access

Maybe I'm not getting it, but I'd think a better name for count would be

IMHO inc (for increment) is better.

add can be read as add key to d
