问题 I am following a tutorial on virtual environments (for Python) from the Coding Train (Here: https://www.youtube.com/watch?v=nnhjvHYRsmM). As I follow the tutorial, I see that, when which python is typed (in Terminal), the output should be the venv's Python in which it had installed.

The commands I use a thousand times a day are: adb kill-server adb connect 192.168.43.1 While Android Studio is not restarted yet, when you type these once, you can use up and down arrow keys to select them. But the problem is that I restart AS or switch between projects so many times a day. And writing these commands over and over again is such a pain. So I thought why don't we create one
