The sequence :: The sequence ::
prog = re.compile(pat) prog = re.compile(pattern)
result = prog.match(str) result = prog.match(string)
is equivalent to :: is equivalent to ::
result = re.match(pat, str) result = re.match(pattern, string)
but the version using :func:`compile` is more efficient when the expression but using :func:`compile` and saving the resulting regular expression object
will be used several times in a single program. for reuse is more efficient when the expression will be used several times
in a single program.
.. (The compiled version of the last pattern passed to :func:`re.match` or .. note::
:func:`re.search` is cached, so programs that use only a single regular
expression at a time needn't worry about compiling regular expressions.) The compiled versions of the most recent patterns passed to
:func:`re.match`, :func:`re.search` or :func:`re.compile` are cached, so
programs that use only a few regular expressions at a time needn't worry
about compiling regular expressions.
