Accidentally deleted /usr/bin/python instead of /usr/local/bin/python, how to restore?

I had so many Python installations that it was getting frustrating, so I decided to do a full reinstall. I removed the /Library/Frameworks/Python.Frameworks/ folder, and meant to remove the /usr/local/bin/python folder too, but I accidentally removed the /usr/bin/python instead. I don’t see any difference, everything seems to be working fine for now, but I’ve read multiple articles online saying that I should never touch /usr/bin/python as OS X uses it and things will break.

I tried Time Machine but there are no viable recovery options. How can I manually “restore” what was deleted? Do I even need to, since everything seems to be working fine for now? I haven’t restarted the Mac yet, in fear that things might break.

Edit: I believe the exact command I ran was rm -rf /usr/bin/python*, and I don’t have anything python related in my /usr/bin/ folder.

Edit2: I’m running on macOS Mojave 10.14.5

¿Cuál es la diferencia entre poner #!/usr/bin/python y no ponerlo

Yo mismo siempre ocupo muchas veces estas lineas #!/usr/bin/python al principio de mi script de python, pero no sé por qué es útil. Tengo entendido que si en la terminal abro script.py con python script.py no me causará problemas si mi script no le anteceden estas líneas. Disculpen la ignorancia 😀
