Python zip function tutorial

If you were using bad practices, however, this can cause you some trouble! Let's see an example! Our vars in the regular for loop are overwriting the originals, compared to the list comprehension, which does not. Python - frozenset. Python - isinstance. Python - issubclass. Python - memoryview. Python - property. This would cause confusion: You may run into IndexErrors as you're accessing items at indices that are no longer valid because the item at the index has been removed, or You may not be accessing newly added items at all as they are at indices not currently in the range of accessed indices.

How Python's zip Function Works Let's start by looking up the documentation for zip and parse it in the subsequent sections. Make an iterator that aggregates elements from each of the iterables.

Returns an iterator of tuples, where the i -th tuple contains the i -th element from each of the argument sequences or iterables. The iterator stops when the shortest input iterable is exhausted.

With a single iterable argument, it returns an iterator of 1-tuples. With no arguments, it returns an empty iterator. Notice how the first tuple at index 0 on the right contains 2 items, at index 0 in L1 and L2 , respectively. The second tuple at index 1 contains the items at index 1 in L1 and L2. In general, the tuple at index i contains items at index i in L1 and L2. Let's try out a few examples in the next section.

Try running the following examples in your favorite IDE. Let's remove 'e' from L2 , and repeat the steps above. Let's revisit the items 3 and 4 of the documentation again.
