    Python re search vs match

    on Mar 5, 2016

    Python re.match() checks for a match only at the beginning of the string, while re.search() checks for a match anywhere in the string. Re search can also act like re match by using caret (^) in the pattern.

    Here are some examples

    re search vs re match

    import re
    print "==re.search=="
    m = re.search('world', "Hello WORLD", re.I)
    print m
    m = re.search('^world', "Hello WORLD", re.I)
    print m
    print "==re.match=="
    m = re.match('hello', "Hello WORLD", re.I)
    print m
    m = re.match('world', "Hello WORLD", re.I)
    print m
    ==re.search==
    <_sre.SRE_Match object at 0x7f6681ab8648>
    None
    ==re.match==
    <_sre.SRE_Match object at 0x7f6681ab8648>
    None
    
    Env: Python 2.7.16

    re search using caret

    import re
    print "==re.search using caret=="
    m = re.search('^hello', "Hello WORLD", re.I)
    print m
    m = re.search('^world', "Hello WORLD", re.I)
    print m
    ==re.search using caret==
    <_sre.SRE_Match object at 0x7fe0342d76b0>
    None
    
    Env: Python 2.7.16
