"This module provides classes and functions for comparing sequences. It can "
"be used for example, for comparing files, and can produce difference "
"information in various formats, including HTML and context and unified "
"diffs. For comparing directories and files, see also, the :mod:`filecmp` "
"module."
msgstr ""

msgid ""
"This is a flexible class for comparing pairs of sequences of any type, so "
"long as the sequence elements are :term:`hashable`. The basic algorithm "
"predates, and is a little fancier than, an algorithm published in the late "
"1980's by Ratcliff and Obershelp under the hyperbolic name \"gestalt pattern "
"matching.\" The idea is to find the longest contiguous matching subsequence "
"that contains no \"junk\" elements; these \"junk\" elements are ones that "
"are uninteresting in some sense, such as blank lines or whitespace. "
"(Handling junk is an extension to the Ratcliff and Obershelp algorithm.) The "
"same idea is then applied recursively to the pieces of the sequences to the "
"left and to the right of the matching subsequence. This does not yield "
"minimal edit sequences, but does tend to yield matches that \"look right\" "
"to people."

"**Timing:** The basic Ratcliff-Obershelp algorithm is cubic time in the "
"worst case and quadratic time in the expected case. :class:`SequenceMatcher` "
"is quadratic time for the worst case and has expected-case behavior "
"dependent in a complicated way on how many elements the sequences have in "
"common; best case time is linear."

"**Automatic junk heuristic:** :class:`SequenceMatcher` supports a heuristic "
"that automatically treats certain sequence items as junk. The heuristic "
"counts how many times each individual item appears in the sequence. If an "
"item's duplicates (after the first one) account for more than 1% of the "
"sequence and the sequence is at least 200 items long, this item is marked as "
"\"popular\" and is treated as junk for the purpose of sequence matching. "
"This heuristic can be turned off by setting the ``autojunk`` argument to "
"``False`` when creating the :class:`SequenceMatcher`."
