Full matching using regular expressions in python

There are many matches in python, such as the search () function at any location and the match () function at the search boundary. Now you need to learn a full match function, that is, the search character matches all the content, and it is the fullmatch () function.

Example:

# Python 3.6 # Cai junsheng # http://blog.csdn.net/caimouse/article/details/51749579#import retext = 'this is some text -- with punctuation. 'pattern' = 'is 'print ('text: ', Text) print ('pattern', pattern) m = re. search (pattern, text) print ('search: ', m) s = re. fullmatch (pattern, text) print ('full match: ', s) text = 'is 'print ('text:', Text) s = re. fullmatch (pattern, text) print ('full match: ', s) text = 'iss' print ('text:', Text) s = re. fullmatch (pattern, text) print ('full match: ', s)

The output is as follows:

Text    : This is some text -- with punctuation.Pattern  : isSearch   : <_sre.SRE_Match object; span=(2, 4), match='is'>Full match : NoneText    : isFull match : <_sre.SRE_Match object; span=(0, 2), match='is'>Text    : issFull match : None
