It accepts a readline-like method which is called repeatedly to get the next line of input (or "" for EOF). It generates 5-tuples with these members: the token type (see token.py) the token (a string) the starting (row, column) indices of the token (a 2-tuple of ints) the ending (row, column) indices of the token (a 2-tuple of ints) the original line (string) It is designed to match the working of the Python tokenizer exactly, except that it produces COMMENT tokens for comments and gives type OP for all operators Older entry points tokenize_loop(readline, tokeneater) tokenize(readline, tokeneater=printtoken) are the same, except instead of generating tokens, tokeneater is a callback function to which the 5 fields described above are passed as 5 arguments, each time a new token is found.sKa-Ping Yee s@GvR, ESR, Tim Peters, Thomas Wouters, Fred Drake, Skip MontanaroiÿÿÿÿN(t*it_tCOMMENTttokenizetgenerate_tokenstNLt untokenizeiicGsddi|ƒdS(Nt(t|t)(tjoin(tchoices((s tokenize.pyctgroup,scGst|ŒdS(NR(R (R ((s tokenize.pyctany-scGst|ŒdS(Nt?(R (R ((s tokenize.pyctmaybe.ss[ \f\t]*s #[^\r\n]*s\\\r?\ns [a-zA-Z_]\w*s0[xX][\da-fA-F]*[lL]?s 0[0-7]*[lL]?s [1-9]\d*[lL]?s [eE][-+]?\d+s\d+\.\d*s\.\d+s\d+s\d+[jJ]s[jJ]s[^'\\]*(?:\\.[^'\\]*)*'s[^"\\]*(?:\\.[^"\\]*)*"s%[^'\\]*(?:(?:\\.|'(?!''))[^'\\]*)*'''s%[^"\\]*(?:(?:\\.|"(?!""))[^"\\]*)*"""s [uU]?[rR]?'''s [uU]?[rR]?"""s&[uU]?[rR]?'[^\n'\\]*(?:\\.[^\n'\\]*)*'s&[uU]?[rR]?"[^\n"\\]*(?:\\.[^\n"\\]*)*"s\*\*=?s>>=?s<<=?s<>s!=s//=?s[+\-*/%&|^=<>]=?t~s[][(){}]s\r?\ns[:;.,`@]s%[uU]?[rR]?'[^\n'\\]*(?:\\.[^\n'\\]*)*t's%[uU]?[rR]?"[^\n"\\]*(?:\\.[^\n"\\]*)*t"s'''s"""sr'''sr"""su'''su"""sur'''sur"""sR'''sR"""sU'''sU"""suR'''suR"""sUr'''sUr"""sUR'''sUR"""trtRtutUsr'sr"sR'sR"su'su"sU'sU"sur'sur"sUr'sUr"suR'suR"sUR'sUR"it TokenErrorcBseZRS((t__name__t __module__(((s tokenize.pycRƒstStopTokenizingcBseZRS((RR(((s tokenize.pycR…sc CsA|\}}|\}}d||||t|t|ƒfGHdS(Ns%d,%d-%d,%d: %s %s(ttok_nametrepr( ttypettokent.2t.3tlinetsrowtscolterowtecol((s tokenize.pyct printtoken‡scCs+yt||ƒWntj onXdS(s: The tokenize() function accepts two parameters: one representing the input stream, and one providing an output mechanism for tokenize().
