[Python-ideas] Add an option for delimiters in bytes.hex()

2017-05-01 Thread robert.hoelzl
The bytes.hex() function is the inverse function of Bytes.fromhex(). But fromhex can process spaces (which is much more readable), while hex() provides no way to include spaces. My proposal would be to add an optional delimiter, that allows to specify a string that will be inserted between the d

2017-05-01 Thread NoxDaFox
The decorators would abstract the logic of spawning a process or thread and maintaining its lifecycle. I think it could be a good fit for the `concurrent.futures` module. Decorated functions would return a `Future` object and run the logic in a separate thread or process. @concurrent.futures.thr
