how to install pandas in python

We find difficulty in installation and pandas mainly when there are multiple versions of python installed on system to avoid confusion use below command:

python -m pip install pandas python -c 'import pandas'

You may replace word 'python' with exact version of python also, if required, eg:

  python3.8 -m pip install pandas 

  python3.8  -c 'import pandas'
