[issue33387] Simplify bytecodes for try-finally, try-except and with blocks.

[issue43026] Missing words renders meaning unclear in fcntl.html

New submission from Ezra : At https://docs.python.org/3/library/fcntl.html the docs read: the fcntl module exposes the F_OFD_GETLK, F_OFD_SETLK and F_OFD_SETLKW constants, which working with open file description locks. The exact intended meaning is unclear, perhaps: the fcntl module exposes

[issue43025] Use normal 'i

Steven D'Aprano added the comment: https://mathworld.wolfram.com/j.html D and SmartBASIC use a literal suffix "i" for imaginary numbers. I can't find any other languages which support literal syntax for complex numbers, but I haven't looked very far. https://www.researchgate.net/profile/Ken

[issue43025] Use normal 'i' character to denote imaginary part of complex numbers

Eric V. Smith added the comment: I don't think it really matters what other languages do. We're not designing this from scratch. We need to reflect that state we're in, which is many, many lines of working code using 'j'. I see the two options as: support 'i' and 'j', or break existing code

Tadek Kijkowski added the comment: >> Is it up to the special handler of the positional parameter to read and save >> the values of the optional parameters specified so far? Yes, in order to get anything more that just concatenated list of positional parameters, one has to provide specialize

Tadek Kijkowski added the comment: This is, I think, smallest functional example for matching optional parameters with positionals - fruits.py: import argparse DEFAULT_COLOR="plain" class AddFruitAction(argparse.Action): def __call__(self, parser, namespace, values, option_st

[issue43025] Use normal 'i' character to denote imaginary part of complex numbers

Steven D'Aprano added the comment: I think it always helps to look at what other languages do. It doesn't mean that we must follow them, but it may help us decide that the choice made in Python 1 was a mistake and it is worth going through the pain of deprecation, or that it is still justifi

[issue41962] Make threading._register_atexit public?

Ben Darnell added the comment: I have resolved my issue here by moving from ThreadPoolExecutor to a plain threading.Thread that I manage by hand (https://github.com/tornadoweb/tornado/commit/15832bc423c33c9280564770046dd6918f3a31b4). Therefore I no longer need this for myself and I leave it

[issue43028] seeking past the end of a file unexpected behavior

New submission from Cotton Seed : Seeking past the end of a file with file objects does not match the same code implemented in terms of file descriptors. Is this the intended behavior? Smallest example I could find: f = open('new_file', 'ab') print(f.seek(1)) print(f.write(b'foo')) print(f.t

[issue43028] seeking past the end of a file unexpected behavior

Christian Heimes added the comment: The high level and low level variants behave the same if you pass in the same flags. You are using the append flag in "open()", but you don't pass the os.O_APPEND flag to "os.open()". >>> import os >>> fd = os.open('log', os.O_WRONLY | os.O_APPEND | os.O_C
