The built-in zip() function aggregates elements from two or more iterables, creating an iterator that yields tuples. Each tuple contains the i-th element from each of the input iterables. The function stops when the shortest iterable is exhausted, ensuring that each tuple is complete:
zip() Signature Arguments Argument Description Default Value *iterables One or more iterables (e.g., lists, tuples, strings) to be zipped together. Required arguments strict A Boolean that, if set to True, raises a ValueError if iterables have different lengths. False Return Value
zip() Examples
With two iterables as arguments:
With more than two iterables:
With a single iterable:
With no arguments:
zip() Common Use Cases
The most common use cases for the zip() function include:
*).zip() Real-World Example
Suppose you have three lists, one containing product names and the others containing their respective prices and stocks. You want to create a dictionary that maps product names to total costs. Here’s how you can do it with the zip() function:
In this example, you use zip() to iterate over the products, prices, and stocks in parallel using a for loop. Then, you construct the desired dictionary by using the products as keys and multiplying the stocks and prices.
