How can I hide columns in Openpyxl?

Question

I'm hiding a bunch of columns in an Excel sheet. I'm getting this error: AttributeError: can't set attribute from this line worksheet.column_dimensions['B'].visible = False

Sorry if this is a super simple question. I just updated to a new version of Openpyxl/Pandas so i'm now having to go through my code and make changes to fit the new version's documentation.

    worksheet.column_dimensions['B'].visible = False
    worksheet.column_dimensions['D'].visible = False
    worksheet.column_dimensions['E'].visible = False
    worksheet.column_dimensions['F'].visible = False

    worksheet.column_dimensions['CU'].visible = False

Also, if someone could tell me if there's a more efficient way to hide the columns, which i'm certain there probably is, that would be great.

Answer 1

You should set the hidden attribute to True:

 worksheet.column_dimensions['A'].hidden= True

In order to hide more than one column:

for col in ['A', 'B', 'C']:
    worksheet.column_dimensions[col].hidden= True
