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
