Python regex split without empty string

Question

I have the following file names that exhibit this pattern:

000014_L_20111007T084734-20111008T023142.txt
000014_U_20111007T084734-20111008T023142.txt
...
         


        

Answer 1

I'm no Python expert but maybe you could just remove the empty strings from your list?

str_list = re.split('^[0-9]+_[LU]_|-|\.txt$', f)
time_info = filter(None, str_list)
