Issue merging 2 excel files

I try to merge two excel file which required " import pandas as pd"
once i do run the codes over at shell getting following
"=== RESTART: C:/Users/myname/AppData/Local/Programs/Python/Python311/ ===
Any suggestion
I went to command line asked to update pip and did that, then ask install openpyxl

Anyone know exactly step by step processes thx!

Here are some thoughts: 1 try removing the ===RESTART message. 2. Are you running a script? At command prompt or terminal, navigate to directory your script is in and run the script using python 3. Do you have pandas and openpyxl installed? If you dont, install them. If you do try updating the libraries (pip install --upgrade pandas openpyxl)
