Notice that the 2nd last line says you have an empty list.
So a[0] will produce an index error since there is no element 0.
You need to check for an empty list before the assignment.
(Or catch the index error in a try/except)
Notice the help for re.findall() says
############################
findall(pattern, string, flags=0)
Return a list of all non-overlapping matches in the string.
If one or more groups are present in the pattern, return a
list of groups; this will be a list of tuples if the pattern
has more than one group.
Empty matches are included in the result.
###########################
See the last line?
BTW Please delete the digest items that are not relevant. These
messages go to the full 400+ members of the list and many pay
by the byte. They don't want to see stuff they have
already received unless it's relevant.
