Python in excel Name error

In general it works. As comment - 1) better to use built in Python Editor instead of one in Excel Labs. 2) print() returns nothing into the grid, output is in panel only

1. Check the Python environment: Make sure that you have installed and configured the Python environment correctly.
Open a command prompt and type python --version to check the Python version.
2. Check Excel add-in: Make sure that the Excel add-in that supports Python (e.g. PyXLL, xlwings, etc.) is installed and enabled.
Open Excel, click “File” > “Options” > “Add-ins” to check if the add-in is enabled.
3. Check code syntax: Check for spelling errors or undefined variables in the Python code.
Make sure that all libraries and functions used have been imported correctly.
4. Use debugging tools: Add print statements to your Python code to output variable values to locate the problem.
Use Python debugging tools (such as pdb) to step through the code.
5. Check Excel cell references: Ensure that the Excel cell references are correct and that the cells contain valid data.
Use xlwings or openpyxl library to read and write Excel cell data.
6. Contact Microsoft Support: If none of the above methods work, it is recommended to contact Microsoft support team and provide detailed error messages and screenshots for further assistance.
