This article will explain in detail how to group python regular expressions. 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.

Grouping

Format:

(\ w)

Note: a pair of parentheses in a regular expression indicates a grouping. There can be multiple groupings in a regular expression.

Use:

Match the string, only extract the content in the group, and discard the content of the non-group and do not extract it.

Case study:

Str1 = 'pythonjavajavascript'''result1 = re.findall (' (\ w+)', str1) print (result1) result2 = re.findall ('\ wicked mother mother str1) print (result2) out: ['python',' java', 'javascript'] [' await, 'baked,' c']

You can see the magic of grouping from the differences in extracting content between result1 and result2, which can specify that content that conforms to a regular expression is extracted.
