yes thank you I had a knowledge gap there I didn't know that you could do that.

I am confused if we dont have to return the list and if I try assigning the list in the function body it will become a local variable and if I try accessing the global statement that also leads to an error and the changes from indexing won't work as its a parameter so How the reversed list is to be given as in not print or return no global variable to change it in so what is to be done I am confused?:(???

Will the matrices go beyond 3x3 matrices??? or under 3x3 matrices please help???
