Adding a directory into PYTHONPATH permanently in Pydroid3

[tobeornottobealttfan]

Hello,

I have some modules in a folder in dropbox which is downloaded in my phone. I want to add that location permanently to the PYTHONPATH so that I can call them whenever I want.

But I am unable to do that.
 

Things I tried.

import sys
import site
site.addsitedir('the path')
print(sys.path)

This was only temporary.

 

2. In pydroid terminal..

export PYTHONPATH = "$PYTHONPATH: the path"

Any help will be much appreciated.

P.S: I don't want to move these files to any other folder as because I want to have a direct connection to my PC where Dropbox folder is added to the pythonpath.

I don't think you can, application storage is sandboxed.

Would it help if I root my phone?

Old thread I know... But my workaround for this issue was to go into Settings->System and change "Interpreter name" to something like this

python3 -i **path to script**

Create a startup script similar to this

import sys
sys.path.append(**path to modules**)

Running python with -i forces an interactive session instead of exiting after the script runs.
