Question

When establishing PYTHONPATH, which terminal window to use? Just the regular terminal window (.bash) that opens when I click on Terminal in Utilities in Applications?

Also, as I add the following line to the end: export PYTHONPATH="/Users/my_user/code", do I add it to this line, which is already there for some reason? : my-MacBook-Air:~ myname$

Also, how do I save this file in Mac?

And finally, what do i substitute this by?: /Users/my_user/code. Is this the path where I installed Python? So, for example, /Macintosh HD/Applications/ ?.

UPDATE: I WAS ABLE TO FIGURE THIS OUT!!!!!!!!!

I guess it would be super helpful if someone could please type an example of the file that needs to be saved. You can use pseudonames in the path like I did above ('myname'). Thanks so much. I'm very new to this.

Answer 1

Firstly, terminal(Terminal.app) needs to be opened. Then we need to open the file ".bash_profile". For which there are different text editors are there. I am assuming that nano text editor is installed on the mac. So the command needs to be executed is " nano .bash_profile " .

Do not worry if something is written in it or not. Just come to the end of the file and write these two lines:

1.PATH="path/where/python/is/installed:{PATH}"

2.export PATH

Now save the file with Ctrl+X on nano editor.

And then just restart the terminal to let it come into effect. After that environment variable is permanently set for python and you can start coding.
