Pulling password and storing in variable in python

I am trying to run a python script directly from VSC. Especially for testing, I am not utilizing powershell and I want to store credentials pulled from OP into a variable, but this is not working... I tried variable=os.system("op read op://url") and this returns the variable as "0". I then tried utilizing a .env file and calling the variables by: os.system("op run --env-file="./envfile.env"") I know I'm doing something wrong, but I just don't know what... I did also try setting the variable from PS, but didn't have luck with that.
