Example Analysis of interval in python regular expression

I would like to share with you the sample analysis of intervals in python regular expressions. I hope you will get something after reading this article. Let's discuss it together.

1. The regular expression engine uses a hyphen (-) to represent an interval in a character group, so you can use [0-9] to match any number.

If we want to match all lowercase letters, we can write [amurz] and all uppercase letters.

2. Intervals can also represent consecutive English alphabet character classes, or multiple different intervals.

Example

A = re.findall (r'[0-9]', 'xxx007abc') b = re.findall (r' [a murz]', 'abc001ABC') c = re.findall (r' [A-Za-z0-9]', 'abc007ABC') d = re.findall (r' [0-9\ -]', '0edu 007 muredu') print (a) print (b) print (c) print (d) finished reading this article I believe you have some understanding of "sample Analysis of intervals in python regular expressions".
