Python re.search: Find Patterns in Strings
The re.search() function is a search function in the re module that is used to search for content matching a specific pattern within a given string. It searches from left to right, stops once it finds a match, and returns the first matching result. If no match is found, it returns None.
Use regular expression to search for a pattern within a string, with an option to specify flags.
Description of parameters:
- Pattern: regular expression pattern to be matched.
- String: the string to be searched.
- flags: optional parameter used to control the matching behavior.
The return value of the re.search() function is a match object, and you can use the group() method to retrieve the matched content.
