searching multiple items with Python re

I am trying to extract hours, mins, seconds and mseconds from a txt file, that may or may not be present in a line. The format is "hh:mm:ss.ms". I know I should so something like this 

int(re.search('(\d+):(\d+):(\d+).(\d+)', current_line).group(1))

but I don't know how to returns these four values to four different variables.

You can call groups on the match object to get a tuple of groups, like this:

match = re.search('(\d+):(\d+):(\d+).(\d+)', current_line)
hour,minute,second,ms = map(int, match.groups())

Well, if you insist on doing it in one line:

hrs, min, sec, msec = (int(group) for group in re.search('(\d+):(\d+):(\d+).(\d+)', current_line).groups())
