ModuleNotFoundError: No module named 'pandas'

getting the above error previously got error for pymongo… now when i tried with pandas its the same Error - ModuleNotFoundError: No module named ‘pandas’

something i am missing seriously… i tried uninstalling and installing python as well but still same error…

can any experts guide me on this.

You have to separately install both those modules from pypi.org

Pandas is not part of Python’s stdlib, and needs to be installed.
Usually you would type:

 python -m pip install pandas

to do this. You may need to adjust the word python to match how you
invoke Python on your system; I understand that on Windows you type py
instead of python.
