Windows does not implement anything equivalent to the POSIX exec family of system calls. The C runtime library implements exec functions by spawning a new process and exiting the current process. So a parent process, such as a shell, that's waiting on the current process will resume, including its console I/O. If it had been up to me, I would have ignored the C runtime exec functions in Windows Python. They only lead to problems with cross-platform code that assumes they work like the POSIX exec functions. Cross-platform code needs to spawn, wait, and proxy the child's exit code. -- https://mail.python.org/mailman/listinfo/python-list
