Python offers different primitive operations based on regular expressions
re.prefixmatch checks for a match only at the beginning of the string re.search checks for a match anywhere in the string (this is what Perl does by default) re.fullmatch checks for entire string to be a match
>>> re.prefixmatch("c", "abcdef") # No match >>> re.search("c", "abcdef") # Match >>> re.fullmatch("p.n", "python") # Match >>> re.fullmatch("r.n", "python") # No match
Regular expressions beginning with '^' can be used with search to restrict the match at the beginning of the string
>>> re.prefixmatch("c", "abcdef") # No match >>> re.search("^c", "abcdef") # No match >>> re.search("^a", "abcdef") # Match
Note however that in MULTILINE mode prefixmatch only matches at the beginning of the string, whereas using search with a regular expression beginning with '^' will match at t
