Hello everyone,This question is just out of curiosity. I am working with this dragon book. From what I have learnt so far, RE uses either NFA or DFA to check whether the string is accepted or not. (Correct?)
So what does the Python's RE module use to check the correctness of the string, NFA or DFA?

In the world of "computer science" regular expressions, yes. But the

Dear group,
I have Excel files that are arranged according to
transctions under various name/directories.
I found out that all these Excel files are not real
OLE based files and some of them are really tab delim

You can do slicing (things like L[:4]) on strings as well as on lists
and tuples. So th
Hi John thanks for the tips
I had a bit of a typo in my first post
time = struct.unpack(">steps",c)
should read somthing more like
time = struct.unpack(">steps+f",c)
adding the f to tell structs it is in float format

seems like it would work but now I cant figure out h

Did you read up on string substitu
Hi Srinivas -
For walking a directory, you can use os.walk() or os.path.walk(), but
I prefer the path module here -

As for determining if a file is really an .XLS format file or a tab
delimited file with .xls on the end, go to www.wotsit.org, have
Hello list
I want to declare a list of a specific size as global to some nested
function like so
def foo (n):
A[] (of size n)
def foo1
...
The only way I can think to declare the list is to use dummy values:
A = [0] * n
A = [] * n doesn't work. [] * n =
