Inasmuch as I would love to post a python script that does the aforementioned task, I rather would urge you to learn the basics of writing codes. Simplify the problem by breaking it down logically on paper. Do not form the habit of asking for codes. Post what you have done so far and let us help solidify your knowledge by guiding you on what to do next or where exactly you seem to be wrong. 1 Like |
