Virtualenv has a Python in its bin? Any source on that?

• jeroenhd 4y ago
  Venvs will actually contain a symlink to a python binary in its venv/bin directory. It doesn't copy a Python executable or download one from the internet as far as I can tell. Still, this means you can install multiple system Python versions and your venv will always contain an executable file of the version the venv was last installed/updated with. ╭─android@localhost ~/tmp/py ╰─$ python3 -m venv testvenv ╭─android@localhost ~/tmp/py ╰─$ file testvenv/bin/python3 testvenv/bin/python3: symbolic link to /data/data/com.termux/files/usr/bin/python3

    There’s a command line flag that will make it create an actual copy, rather than a symlink.

      It's a copy on windows too.

  Venv creates a /bin in it's environment dir that symlinks the Python version used to initialize it or as specified. That's it's entire basic model of operation and takes a few seconds to verify.
