re.match() - Match from String Beginning
How to match the beginning part of a target string with a regular expression using re.match()?
✍: FYIcenter.com
The re.match() function allows you to match the beginning part of a target string
with of a given regular expression.
import re m = re.match(pattern, string, flags=0) Where: pattern is the regular expression string is the target string m is None or a Match object
If the beginning part of the string matches the regular expression, m is the Match object representing the match result.
The behavior of re.match() is the same as re.search() except that the match must start from the beginning of the target string.
Here is Python example that shows you how to use the re.findall() function:
>>> import re >>> s = "Hello perl.org, php.net, and python.org!" >>> p = "(\\w+)\\.(\\w+)" >>> print(p) (\w+)\.(\w+) >>> m = re.match(p,s) >>> print(m) None >>> p = "[^ ]+ (\\w+)\\.(\\w+)" >>> print(p) [^ ]+ (\w+)\.(\w+) >>> m = re.match(p,s) >>> print(m) <_sre.SRE_Match object; span=(0, 14), match='Hello perl.org'> >>> m.group() 'Hello perl.org' >>> m.groups() ('perl', 'org')
⇒ re.sub() - Substitute Matches with String
⇐ re.findall() - Find All Matches
