The most direct way of duplicating the Unix idiom of forking a child process is to use the os.fork function, which is (I believe) just a thin wrapper around the C fork function. https://docs.python.org/3/library/os.html#os.fork But this is not platform-independent, it is Unix only. Alternatively, you can look at the various os.exec* functions, which are available on Windows and Unix, and see if any of them are useful. But the best way to solve this in a platform independent way is to use one of the concurrency modules: https://docs.python.org/3/library/concurrency.html such as multiprocessing. Although these are written for Python 2 rather than 3, you may find them useful: http://pymotw.com/2/multiprocessing/index.html#module-multiprocessing https://www.ibm.com/developerworks/aix/library/au-multiprocessing/ -- Steven -- https://mail.python.org/mailman/listinfo/python-list
