Environment Variables in Python on Linux

Question

Python\'s access to environment variables does not accurately reflect the operating system\'s view of the processes environment.

os.getenv and os.environ do not func

Answer 1

I don't believe many programs EVER expect to have their environment externally modified, so loading a copy of the passed environment at startup is equivalent. You have simply stumbled on an implementation choice.

If you are seeing all the set-at-startup values and putenv/setenv from within your program works, I don't think there's anything to be concerned about. There are far cleaner ways to pass updated information to running executables.
