tokenize — Tokenizer for Python source Source code: Lib/tokenize.py The tokenize module provides a lexical scanner for Python source code, implemented in Python. The scanner in this module returns comments as tokens as well, making it useful for implementing “pretty-printers”, including colorizers for on-screen display... | python.library.tokenize |
tokenize.detect_encoding(readline)
The detect_encoding() function is used to detect the encoding that should be used to decode a Python source file. 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... | python.library.tokenize#tokenize.detect_encoding |
tokenize.generate_tokens(readline)
Tokenize a source reading unicode strings instead of bytes. Like tokenize(), the readline argument is a callable returning a single line of input. However, generate_tokens() expects readline to return a str object rather than bytes. The result is an iterator yielding named tuples, e... | python.library.tokenize#tokenize.generate_tokens |
tokenize.open(filename)
Open a file in read only mode using the encoding detected by detect_encoding(). New in version 3.2. | python.library.tokenize#tokenize.open |

docstring
or: [1,
2,
3 | python.library.tokenize#tokenize.TokenError |
tokenize.tokenize(readline)
The tokenize() generator requires one argument, readline, which must be a callable object which provides the same interface as the io.IOBase.readline() method of file objects. Each call to the function should return one line of input as bytes. The generator produces 5-tuples with these mem... | python.library.tokenize#tokenize.tokenize |
tokenize.untokenize(iterable)
Converts tokens back into Python source code. The iterable must return sequences with at least two elements, the token type and the token string. Any additional sequence elements are ignored. The reconstructed script is returned as a single string. The result is guaranteed to tokenize ba... | python.library.tokenize#tokenize.untokenize |

traceback.extract_tb(tb, limit=None)
Return a StackSummary object representing a list of “pre-processed” stack trace entries extracted from the traceback object tb. It is useful for alternate formatting of stack traces. The optional limit argument has the same meaning as for print_tb(). A “pre-processed” stack trace ... | python.library.traceback#traceback.extract_tb |
traceback.format_exc(limit=None, chain=True)
This is like print_exc(limit) but returns a string instead of printing to a file. | python.library.traceback#traceback.format_exc |

Format the exception part of a traceback. The arguments are the exception type and value such as given by sys.last_type and sys.last_value.

traceback.print_exc(limit=None, file=None, chain=True)
This is a shorthand for print_exception(*sys.exc_info(), limit, file,
chain). | python.library.traceback#traceback.print_exc |
traceback.print_exception(etype, value, tb, limit=None, file=None, chain=True)
Print exception information and stack trace entries from traceback object tb to file. This differs from print_tb() in the following ways: if tb is not None, it prints a header Traceback (most recent
call last):
it prints the exception et... | python.library.traceback#traceback.print_exception |
traceback.print_last(limit=None, file=None, chain=True)
This is a shorthand for print_exception(sys.last_type, sys.last_value,
sys.last_traceback, limit, file, chain). In general it will work only after an exception has reached an interactive prompt (see sys.last_type). | python.library.traceback#traceback.print_last |
traceback.print_stack(f=None, limit=None, file=None)
Print up to limit stack trace entries (starting from the invocation point) if limit is positive. Otherwise, print the last abs(limit) entries. If limit is omitted or None, all entries are printed. The optional f argument can be used to specify an alternate stack fr... | python.library.traceback#traceback.print_stack |
traceback.print_tb(tb, limit=None, file=None)
Print up to limit stack trace entries from traceback object tb (starting from the caller’s frame) if limit is positive. Otherwise, print the last abs(limit) entries.

classmethod extract(frame_gen, *, limit=None, lookup_lines=True, capture_locals=False)
Construct a StackSummary object from a frame generator (such as is returned by walk_stack() or walk_tb()). If limit is supplied, only this many frames are taken from frame_gen. If lookup_lines is Fa... | python.library.traceback#traceback.StackSummary |
classmethod extract(frame_gen, *, limit=None, lookup_lines=True, capture_locals=False)
Construct a StackSummary object from a frame generator (such as is returned by walk_stack() or walk_tb()). If limit is supplied, only this many frames are taken from frame_gen. If lookup_lines is False, the returned FrameSummary ob... | python.library.traceback#traceback.StackSummary.extract |
format()
Returns a list of strings ready for printing. Each string in the resulting list corresponds to a single frame from the stack.

For long sequences of the same frame and line, the first few ... | python.library.traceback#traceback.StackSummary.format |
classmethod from_list(a_list)
Construct a StackSummary object from a supplied list of FrameSummary objects or old-style list of tuples. Each tuple should be a 4-tuple with filename, lineno, name, line as the elements. | python.library.traceback#traceback.StackSummary.from_list |

The me... | python.library.traceback#traceback.TracebackException.format |
format_exception_only()
Format the exception part of the traceback. The return value is a generator of strings, each ending in a newline. Normally, the generator emits a single string; however, for SyntaxError exceptions, it emits several lines that (when printed) display detailed information about where the syntax e... | python.library.traceback#traceback.TracebackException.format_exception_only |
classmethod from_exception(exc, *, limit=None, lookup_lines=True, capture_locals=False)
Capture an exception for later rendering. limit, lookup_lines and capture_locals are as for the StackSummary class. Note that when locals are captured, they are also shown in the traceback. | python.library.traceback#traceback.TracebackException.from_exception |
