# Write strings that looks like numbers. This will cause an Excel warning.

# Write a divide by zero formula. This will also cause an Excel warning.

# Turn off some of the warnings:
worksheet.ignore_errors(

# Write some descriptions for the cells and make the column wider for clarity.

worksheet.write('B3', 'Warning turned off:')
worksheet.write('B5', 'Warning:')
