How can I filter by numbers in an excel sheet using Python codes?

Question

I am trying to filter out the data from my excel sheet using Python. When I filter by car "Make" and "Model," it works fine, but when I add a "Year," it does not return any data(Empty). It works with me only if I add any text at the beginning of each cell for the "Year" Column. How can I get the program to filter without adding text to every cell in the "Year" column.
