You don't give a sample of the code that doesn't work the way you expect, so
I can only guess what your exact problem is.  I seem to recall that
iter(file) doesn't well with file.readline due to the way iter file buffers,
but it's easy to work around:

    lines = iter(file_obj)
    for line in lines:
        if shouldSkipNextLine(line):
            lines.next()

(I'm guessing your code looked something like:

    for line in file_obj:
        if shouldSkipNextLine(line):
            file_obj.readline()
)

If this doesn't answer your question, be more specific about what your
problem is.
