Module difflib
helpers for computing deltas between objects.

Function get_close_matches(word, possibilities, n=3, cutoff=0.6): Use SequenceMatcher to return list of the best "good enough" matches.

Function context_diff(a, b): For two lists of strings, return a delta in context diff format.

Function ndiff(a, b): Return a delta: the difference between `a` and `b` (lists of strings).

Function restore(delta, which): Return one of the two sequences that generated an ndiff delta.

Function unified_diff(a, b): For two lists of strings, return a delta in unified diff format.

Class SequenceMatcher: A flexible class for comparing pairs of sequences of any type.

Class Differ: For producing human-readable deltas from sequences of lines of text.

Class HtmlDiff: For producing HTML side by side comparison with change highlights.
