Given that you talk about using itertools.izip(), I'm going to assume you are using Python 2 here.. Use itertools.islice() to facilitate skipping lines from files, and the itertools.izip_longest() function to lazily combine reading in parallel as well as handle files that are shorter:. These examples are extracted from open source projects. Is there any way to solve this? New comments cannot be posted and votes cannot be cast.

Itertools recipes-----``fn.uniform`` provides you with "unification" of lazy functionality for few functions to work the same way in Python 2+/3+: - ``map`` (returns ``itertools.imap`` in Python 2+) - ``filter`` (returns ``itertools.ifilter`` in Python 2+) - ``reduce`` (returns ``functools.reduce`` in Python 3+) Iteration stops whenever one of the lists is exhausted. *.pyi files that describe entire packages (directories containing __init__.py) should be placed in the package directory's parent directory. Since it only returns references to the list, the list should not be modified outside the generator. dict(itertools.izip_longest(s.split(), (value1, value2, option1, option2), None)) Mikko Ohtamaa on 2010-04-17 at 18:36 said: I can write a helper function for my application regarding the problem any day and I have already done so *many times*. 7 comments Comments. PyCharm's on-the-fly inspection immediately detects unresolved references, and highlights them with the red curvy line. Work well also with multiple copies of elements in the input list. In this post i will try to explain for what purpose it can be used and how. try: from itertools import zip_longest except ImportError: from itertools import izip_longest as zip_longest Instead of. This thread is archived. Other forms of forward references will not work in the source code due to out-of-order class and function definitions. I use some of the tools built into python's itertools, such as chain, and zip_longest which returns an iterable which can be iterated through using a for loop.
