zip
zip(*iterables, strict=False)
Iterate over several iterables in parallel, producing tuples with an item from each one.
a = zip([1, 2, 3], ["sugar", "spice", "everything nice"])
print(a) # -> <zip object at 0x7f34987f4380>
for item in zip([1, 2, 3], ["sugar", "spice", "everything nice"]):
print(item)
Output:
(1, 'sugar')
(2, 'spice')
(3, 'everything nice')
More formally: zip() returns an iterator of tuples, where the i-th tuple contains the i-th element from each of the argument iterables.
By default, zip() stops when the shortest iterable is exhausted. It will ignore the remaining items in the longer iterables, cutting off the result to the length of the shortest iterable
zip() is often used in cases where the iterables are assumed to be of equal length. In such cases, it’s recommended to use the strict=True option. Its output is the same as regular zip(). Unlike the default behavior, it raises a ValueError if one iterable is exhausted before the others.
