I checked the doc: _putenv("VAR=") removes the environment variable "VAR". It's well documented:
https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/putenv-wputenv?view=vs-2019
"You can remove a variable from the environment by specifying an empty value_string, or in other words, by specifying only varname=."
So Python 3.8 os._unsetenv() is correct, but this function was not exposed, and so this issue remains relevant: Python 3.8 documents that os.unsetenv() is available on Windows, but it's not. |
