Akira Li added the comment: Two minor details: 1. It is possible that `fileno(stdout) != 1` even in C [1]. I don't know what happens if the code from the answer is run on Windows. In principle, it may break eryksun's workaround. I don't know how likely it is in practice. 2. you can redirect at the file descriptor level in Python [2] using os.dup2().
