pip how to check if we are inside the virtual environment

pip -V is the option  

When not in the virual environment, it gives the path in the system 

(base) REKUMARM-M-WB8Y:server userrm$ pip -V

pip 20.2.4 from /opt/anaconda3/lib/python3.8/site-packages/pip (python 3.8)

now if we are inside the virual env, it gives the pip from the path of virtual env 

for e.g. like this below 

(base) REKUMARM-M-WB8Y:server userrm$ source venv/bin/activate

(venv) (base) REKUMARM-M-WB8Y:server userrm $ pip -V

pip 20.1.1 from /Users/userrm/Documents/CR/projects/POCs/BW2/server/venv/lib/python3.8/site-packages/pip (python 3.8)
