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.zKa-Ping Yee z@GvR, ESR, Tim Peters, Thomas Wouters, Fred Drake, Skip MontanaroN)BOM_UTF8lookup)*)tokencCsg|]}|ddkr|qS)r_).0xrr//usr/lib64/python3.10/lib2to3/pgen2/tokenize.py %r )tokenizegenerate_tokens untokenizecGsdd|dS)N(|))joinchoicesrrr group0r rcGs t|dS)Nrrrrrr any1r rcGs t|dS)N?rrrrr maybe2r rcstfddDS)Nc3s4|],}dD]}||kr||VqqdS))N)casefold)r r ylrr 4sz _combinations..)setrrrr _combinations3s r#z[ \f\t]*z #[^\r\n]*z\\\r?\nz\w+z0[bB]_?[01]+(?:_[01]+)*z(0[xX]_?[\da-fA-F]+(?:_[\da-fA-F]+)*[lL]?z0[oO]?_?[0-7]+(?:_[0-7]+)*[lL]?z[1-9]\d*(?:_\d+)*[lL]?z0[lL]?z[eE][-+]?\d+(?:_\d+)*z\d+(?:_\d+)*\.(?:\d+(?:_\d+)*)?z\.\d+(?:_\d+)*z \d+(?:_\d+)*z\d+(?:_\d+)*[jJ]z[jJ]z[^'\\]*(?:\\.[^'\\]*)*'z[^"\\]*(?:\\.[^"\\]*)*"z%[^'\\]*(?:(?:\\.|'(?!''))[^'\\]*)*'''z%[^"\\]*(?:(?:\\.|"(?!""))[^"\\]*)*"""z'(?:[uUrRbBfF]|[rR][fFbB]|[fFbBuU][rR])?'''"""z'[^\n'\\]*(?:\\.[^\n'\\]*)*'z"[^\n"\\]*(?:\\.[^\n"\\]*)*"z\*\*=?z>>=?z<<=?z<>z!=z//=?z->z[+\-*/%&@|^=<>]=?~z[][(){}]z\r?\nz:=z[:;.,`@]z'[^\n'\\]*(?:\\.[^\n'\\]*)*'z"[^\n"\\]*(?:\\.[^\n"\\]*)*"rRfFbB>UZUrurZURuZuR)r'r(r$r%cCsi|]}|dtqSr$) single3progr prefixrrr yr r6cCsi|]}|dtqSr%) double3progr4rrr r6zr cCsi|] }|dqSNrr4rrr r6{r cCsh|]}|dqSr2rr4rrr r r:cCsh|]}|dqSr7rr4rrr r:r cCsh|]}|dqS)r'rr4rrr r:r cCsh|]}|dqS)r(rr4rrr r:r c@s eZdZdS) TokenErrorN__name__ __module__ __qualname__rrrr r<r r<c@s eZdZdS)StopTokenizingNr=rrrr rAr rAc Cs4|\}}|\}}td||||t|t|fdS)Nz%d,%d-%d,%d: %s %s)printtok_namerepr) typerZxxx_todo_changemeZxxx_todo_changeme1lineZsrowZscolZerowZecolrrr printtokens rGcCs&zt||Wnty Yn0dS)a: The tokenize() function accepts two parameters: one representing the input stream, and one providing an output mechanism for tokenize().

It requires one argument, readline, in the same way as the tokenize() generator. It will call readline a maximum of twice, and return the encoding used (as a string) and a list of any lines (left as bytes) it has read in. It detects the encoding from the presence of a utf-8 bom or an encoding cookie as specified in pep-0263. If both a bom and a cookie are present, but disagree, a SyntaxError will be raised. If the encoding cookie is an invalid charset, raise a SyntaxError. Note that if a utf-8 bom is found, 'utf-8-sig' is returned. If no encoding is specified, then the default of 'utf-8' will be returned.
