How python uses the zip () function

This article will explain in detail how python uses the zip () function. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Zip ()

Earlier, when we introduced the map () function, we gave an example of applying a function to two parallel lists, and the zip () function makes it easier to do this.

If we have two lists, the first list contains the first name and the second list contains the last name. Using the zip () function, we can splice them together as follows.

> first_names = ["Peter", "Christian", "Klaus"] > last_names = ["Jensen", "Smith", "Nistrup"] > print (['.join (x) for x in zip (first_names, last_names)]) [' Peter Jensen', 'Christian Smith',' Klaus Nistrup']

In other words, zip turns two equal-length lists into pairs, namely (("Peter", "Jensen"), ("Christian", "Smith"), ("Klaus", "Nistrup")).
