Match () and search () are regular match functions in Python, so what's the difference between these two functions?
The match () function only detects whether the re is matched at the beginning of a string, and search () scans the entire string for matching, which means
. '>>> Datepat.findall (text)[(' 11 ', ' 27 ', ' 2012 '), (' 3 ', ' 13 ', ' 2013 ')]>>> for month, day, year in Datepat.findall (text):... print (' {}-{}-{} '. Format (year, month, day))...2012-11-272013-3-136. Iterate back Finditer ()The FindAll () method searches for text and returns all matches as a list. If you want to return in an iterative way>>> for M in Datepat.finditer (text):... print (m.groups ())...(' 11 ', ' 27 ', ' 2012 ')(' 3 ', ' 13 ', ' 2013 ')The core step is to use Re.compile
