Finding and copying files with python.

[gtb]

I wish to copy   the highest version number of a file from directory \
\
\fileserver\D:\scripts to C:\scripts where the file names are of the
form

filename_MM.NN.SS.zip, where MM, NN, and SS can be one to three
digits.

Example directory:
other.zip
dx_ver_1.1.63.zip
dx_ver_1.2.01.zip
dx_ver_1.12.7.zip
temp.txt


Does python have string matching routines  that would find the bottom
listed zip file and/or file copying routines?

A little pointer or two would be much appreciated.

Thanks,
