Editor to share with you how to use grouping in python regular expressions. I hope you will get something after reading this article. Let's discuss it together.

1. Grouping is a string as a whole quantifier, putting the whole string in a pair of parentheses.

2. Grouping regular expressions does not require the use of quantifiers in a string as a whole, and existing groupings can also be referenced in regular expressions.

Example

Import re p = r'(121) {2}'m = re.search (p, '121121abcabc') print (m) print (m.group ()) # returns the matching string print (m.group (1)) # returns the first set of content p = r'(\ d {3pm 4})-(\ d {7pm 8}) m = re.search (p '010-87654321') print (m) print (m.group ()) # returns the matching string print (m.groups ()) # to get all the group content after reading this article I believe you have a certain understanding of "how to use grouping in python regular expressions".
