Set python interpreter on a per project bases

Question

I know i can set an interpreter with the code below, is there a way i can set this per project so that when I open emacs with a specific project it selects the interpreter for that project.

(setq python-shell-interpreter "/docker:root@django_web_1:/usr/local/bin/python")

currently i am doing this manually and want a better way as each project runs in its own containers and I often switch projects.

You can set it as a directory-local variable. This is documented in section 51.2.5 Per-Directory Local Variables of the Emacs manual. You can use C-h i to open the manual, or view it online at https://www.gnu.org/software/emacs/manual/html_node/emacs/Directory-Variables.html.
