for loops in python

Is there a pythonic way (I know I can loop using range(len(..)) and get an index) to do the following example:

for line in list_of_strings:
    if line[0] == '$':
        while line[-1] == '#':
            # read in the Next line and do stuff
        # after quitting out of the while loop, the next iteration of the for loop
        # should not get any of the lines that the while loop already dealt with

essentially, the nested while loop should be incrementing the for loop.

Edit: Not a file handle, confused two things I was working on, it's a list of strings
