Python array copy Copy implementation method, python array copy Copy

This article describes how to copy and copy python arrays. Share it with you for your reference. The specific analysis is as follows:

In python, assigning values by equal signs is actually just passing the reference address.
For example:

A = [1, 2, 3, 4, 5] B =

When the value of a changes, the value of B also changes.

If you want B to have nothing to do with a, you can use the following method

A = [1, 2, 3, 4, 5] B = a [:]

In this way, a and B are two completely independent arrays, which do not affect each other.

I hope this article will help you with Python programming.
