name 'rows' is not defined

It seems like you're encountering an error in your code. The error message "name 'rows' is not defined" typically occurs when you try to use a variable that has not been defined or declared before.

To fix this issue, you need to make sure that the variable "rows" is defined before you use it. This can be done by assigning a value to the "rows" variable using an appropriate data type, such as a list or an array.

For example:

rows = [1, 2, 3, 4, 5]  # Define the variable "rows" as a list

Make sure to check your code and ensure that the variable "rows" is defined and accessible in the scope where you are using it.
