SearchObj = re.search( r'dogs', line, re.M|re.I) MatchObj = re.match( r'dogs', line, re.M|re.I) Python offers two different primitive operations based on regular expressions: match checks for a match only at the beginning of the string, while search checks for a match anywhere in the string (this is what Perl does by default) Example #!/usr/bin/python oup(2) : smarter Matching Versus Searching

When the above code is executed, it produces following result - oup() : Cats are smarter than dogs We use group(num) or groups() function of match object to get matched expression Sr.No The re.search function returns a match object on success, none on failure. This is the string, which would be searched to match the pattern anywhere in the string Here is the syntax for this function - re.search(pattern, string, flags=0) This function searches for first occurrence of RE pattern within string with optional flags This method returns all matching subgroups in a tuple (empty if there weren't any) This method returns entire match (or specific subgroup num) The re.match function returns a match object on success, None on failure. These are modifiers, which are listed in the table below You can specify different flags using bitwise OR (|).
This is the string, which would be searched to match the pattern at the beginning of string This is the regular expression to be matched Here is the description of the parameters - Sr.No Here is the syntax for this function - re.match(pattern, string, flags=0)
This function attempts to match RE pattern to string with optional flags To avoid any confusion while dealing with regular expressions, we would use Raw Strings as r'expression' The match Function There are various characters, which would have special meaning when they are used in regular expression
