Support shebang #!/usr/bin/env python{2,3}

One of the best practices for managing Python versions across operating systems is the shebang ‘#!/usr/bin/env python3’. To get around the lack of support for this practice, it seems that the user has to add changes to each individual workspace to set Python versions. Note that setting the ‘Python: Select interpreter’ is also ignored by VSCode.

It would be helpful if maintainers were transparent about whether they have interest or will accept a PR from someone else contributing a fix. This issue was closed in the upstream repo multiple times and not left as open.

Actual behavior

shebang is ignored

Expected behavior

shabang is respected

Steps to reproduce:

Create file:

#!/usr/bin/env python3
import sys
print(sys.executable)

Run it.

Environment data

VS Code version: 1.19.1 Python Extension version: 0.9.1 Python Version: 3.6.4 OS and version: macOS 10.13.2

we purposefully don’t not automatically select what the shebang sets because what someone set for their code may not be what you want to use

As I said in #3689, this is perfectly reasonable default behavior, but the option to enable such automatic functionality would be great.

Ok, looks like you are not using the Python extension to run the python program. You seem to be using another extension such as Code Runner. I’m closing this issue as the output of the output panel is a clear indication of the above fact.

Solution is to use the debug menu or the corresponding debug icons (F5 or CTRL+F5 or similar).
