Iterators terminating on the shortest input sequence

This category is very interesting. It allows you to create an iterator based on multiple iterators, combining their values according to some logic. The key point here is that among those iterators, in case any of them are shorter than the rest, the resulting iterator won't break, it will simply stop as soon as the shortest iterator is exhausted. This is very theoretical, I know, so let me give you an example using compress. This iterator gives you back the data according to a corresponding item in a selector being True or False:

compress('ABC', (1, 0, 1)) would give back 'A' and 'C', because they correspond to 1. Let's see a simple example:

# compress.pyfrom itertools import compressdata ...
