This article will explain in detail how python uses re.match. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Re.match

Re.match attempts to match all or part of a pattern at the beginning of a string, such as: the following example matches the first word.

Import retext = "PythonTab.com is a good Python website" m = re.match (r "(\ w +)\ s", text) if m:print m.group (0),'\ nforth, m.group (1) else:

The function prototype of re.match is: re.match (pattern, string, flags)

The first parameter is a regular expression, where it is "(\ w +)\ s". If the match is successful, a Match is returned, otherwise a None is returned.

The second parameter represents the string to match

The third parameter is the Peugeot bit, which controls how regular expressions are matched, such as case sensitivity, multiline matching, and so on.

Note: it can be matched on the premise that the matching conditions must be met in the first place
