Unable to remove env variable from .bash_profile

Question

I have a few problems regarding the use of .bash_profile and Pycharm. I am using mac OS X. I created a new project on pycharm with new environment using virtualenv with base interpreter /usr/local/bin/python3.5.

STEP 1: I then accessed the .bash_profile from my mac OS terminal and exported 2 variables: DB_USER and DB_PASS as my_db_user and my_db_pass respectively.

STEP 2: Using Pycharm, I imported os and then proceeded to print out the 2 variables using os.environ.get(). Running the .py file using pycharm (F10) returns my_db_user and my_db_pass.

As I decided to create 2 new variables test user and test pass in the virtual environment, I proceeded to activate my venv (venv/bin/activate) in the shell of pycharm. Then, I removed the changes I did in STEP 1.

However, running the .py using pycharm (F10) STILL returns my_db_user and my_db_pass instead of test user and test pass (I have already removed my_db_user and my_db_pass so I have no idea where it is coming from!). On top of that, when I run the python file on the shell using python test.py, it returns (None, None) instead of my desired test user and test pass.

I need help to sort this out so that os.environ.get() returns my desired output. One possible reason is that I might be confused on how pycharm, shell in pycharm and terminals are interacting. Please help thanks!

import os user = os.environ.get('DB_USER') password = os.environ.get('DB_PASS') print(user,password)

If I read your post correctly, you have already cleared out the .bash_profile file, so what remains is just running

unset DB_USER DB_PASS

in each shell window that still has the environment variables.

also, check if the variables have been written to your ~/.bash_profile and if they have, remove them. then run: source ~/.bash_profile

it worked, thank you. If possible, I would like to know why using unset command is required on top of clearing of .bash_profile. And, is there a difference between nano .bash_profile and nano ~/.bash_profile?
