Python's zip(~) method combines the elements from the provided iterables and returns it as an iterator of tuples.

Parameters

1. iterables | iterables

The iterables to combine. Can specify multiple.

Return value

An iterator of tuples from the provided input iterables.

Examples

Basic usage

To combine two lists of students and their corresponding score:

students = ['Bob', 'Tom', 'Daisy']
scores = [55, 70, 60]

combined = zip(students, scores)
print([*combined])
[('Bob', 55), ('Tom', 70), ('Daisy', 60)]

Note that the first tuple contains the first element from each of the two input lists, second tuple contains second element etc. In the last line we unpack the results into a list.

Different length iterables

Zip will stop once the shorter iterable has been exhausted:

students = ['Bob', 'Tom', 'Daisy', 'Mandy']
scores = [55, 70, 60]

combined = zip(students, scores)
print([*combined])
[('Bob', 55), ('Tom', 70), ('Daisy', 60)]

Here we see that the we stop after three pairs as scores list is exhausted.
