Editor to share with you how to use the Python list guide, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

List derivation (also known as list parsing) provides a concise way to create lists.

Description

1. Its structure is to contain expressions in parentheses, followed by for statements, followed by 0 or more for or if statements.

2. The expression can be arbitrary, and any type of object can be put in the list.

The result returns a new list, generated after the transportation of the expression above and below the if and for statements is complete.

Example

List derivation is great in some cases, especially if you need to use the list for loop to generate a new list. For example, most people usually do this:

Squared = [] for x in range (10): squared.append (Xerox 2)

You can simplify it by using the following list derivation:

Squared = [x examples 2 for x in range (10)] these are all the contents of the article "how to use Python list derivation". Thank you for reading!
