difflib.ndiff(a, b, linejunk=None, charjunk=IS_CHARACTER_JUNK) Compare a and b (lists of strings); return a Differ-style delta (a generator generating the delta lines). Optional keyword parameters linejunk and charjunk are filtering functions (or None): linejunk: A function that accepts a single string argument, and returns true if the string is junk, or false if not. The default is None. There is also a module-level function IS_LINE_JUNK(), which filters out lines without visible characters

difflib.IS_LINE_JUNK(line) Return true for ignorable lines. The line line is ignorable if line is blank or contains a single '#', otherwise it is not ignorable. Used as a default for parameter linejunk in ndiff() in older versions.

difflib.IS_CHARACTER_JUNK(ch) Return true for ignorable characters. The character ch is ignorable if ch is a space or tab, otherwise it is not ignorable. Used as a default for parameter charjunk in ndiff().

__init__(tabsize=8, wrapcolumn=None, linejunk=None, charjunk=IS_CHARACTER_JUNK) Initializes instance of HtmlDiff. tabsize is an optional keyword argument to specify tab stop spacing and defaults to 8. wrapcolumn is an optional keyword to specify column number where lines are broken and wrapped, defaults to None where lines are not wrapped. linejunk and charjunk are optional keyword arguments passed into ndiff() (used by HtmlDiff to generate the side by side HTML differences). See ndiff() doc

make_table(fromlines, tolines, fromdesc='', todesc='', context=False, numlines=5) Compares fromlines and tolines (lists of strings) and returns a string which is a complete HTML table showing line by line differences with inter-line and intra-line changes highlighted. The arguments for this method are the same as those for the make_file() method.

make_file(fromlines, tolines, fromdesc='', todesc='', context=False, numlines=5, *, charset='utf-8') Compares fromlines and tolines (lists of strings) and returns a string which is a complete HTML file containing a table showing line by line differences with inter-line and intra-line changes highlighted. fromdesc and todesc are optional keyword arguments to specify from/to file column header strings (both default to an empty string). context and numlines are both optional keyword arguments.

class difflib.HtmlDiff This class can be used to create an HTML table (or a complete HTML file containing the table) showing a side by side, line by line comparison of text with inter-line and intra-line change highlights. The table can be generated in either full or contextual difference mode. The constructor for this class is: __init__(tabsize=8, wrapcolumn=None, linejunk=None, charjunk=IS_CHARACTER_JUNK) Initializes instance of HtmlDiff. tabsize is an optional keyword argument to speci

difflib.get_close_matches(word, possibilities, n=3, cutoff=0.6) Return a list of the best “good enough” matches. word is a sequence for which close matches are desired (typically a string), and possibilities is a list of sequences against which to match word (typically a list of strings). Optional argument n (default 3) is the maximum number of close matches to return; n must be greater than 0. Optional argument cutoff (default 0.6) is a float in the range [0, 1]. Possibilities that don’t sc

difflib.diff_bytes(dfunc, a, b, fromfile=b'', tofile=b'', fromfiledate=b'', tofiledate=b'', n=3, lineterm=b'\n') Compare a and b (lists of bytes objects) using dfunc; yield a sequence of delta lines (also bytes) in the format returned by dfunc. dfunc must be a callable, typically either unified_diff() or context_diff(). Allows you to compare data with unknown or inconsistent encoding. All inputs except n must be bytes objects, not str. Works by losslessly converting all inputs (except n) to

compare(a, b) Compare two sequences of lines, and generate the delta (a sequence of lines). Each sequence must contain individual single-line strings ending with newlines. Such sequences can be obtained from the readlines() method of file-like objects. The delta generated also consists of newline-terminated strings, ready to be printed as-is via the writelines() method of a file-like object.
