difflib.ndiff()
difflib.ndiff() is a Python function in the Difflib Module category. Compares sequences and produces a human-readable delta (like diff). The syntax is difflib.ndiff(a, b, linejunk=None, charjunk=None). Returns: Iterator of diff lines. A typical example: diff = difflib.ndiff(["a\n","b\n"], ["a\n","c\n"])
print("".join(diff)). A close sibling is difflib.SequenceMatcher(), which flexible sequence comparison object. Finds the longest matching subsequences. A close sibling is difflib.get_close_matches(), which returns the best `n` matches for a word from a list of possibilities. A close sibling is difflib.unified_diff(), which compares two sequences and produces a unified diff output (like diff -u). A close sibling is difflib.context_diff(), which compares sequences and produces a context diff (like diff -c).
