[issue27805] In Python 3, open('/dev/stdout', 'a') raises OSError with errno=ESPIPE

[Antti Haapala]

Antti Haapala added the comment:

Yeah, it definitely is a bug in CPython. open(mode='a') should always append to the end of the given file. 

If you're writing an append-only text log to some file-like object, that's the mode you use, not some version/platform/filesystem specific voodoo to find out what's the least incorrect way to work around Python implementation deficiencies.
