Python topic-----The difference between search () and match ()

1. The match () function only detects if the re is matched at the start of the string, which means that match () returns only if the 0-bit match succeeds, and if the match () is not successful, match () returns none

2. Search () scans the entire string lookup match

For example:

Import reprint (Re.match ("Good", "Morning Good"). Span ()) #报错分会none

Print (Re.match ("Good", "Good Morning"). span ()) #成功

Print (Re.search ("Good", "Morning Good OK"). span ()) #成功
