mov = open(afile)
for i,line in enumerate(mov):
    if not i: # Enumeration starts at zero so it is the first line
        continue # Use continue to just move to the next iteration if
you
                 # don't want/need to do anything
        # or you can do a check for what you were looking for
        if ':' in line:
            break
    # Alternatively you could do it as
    if not i and ':' in line:
        break

    # Perform your normal operations on the file, not exactly clear
what you
    # want to perform
