Create a python function that takes in a 2d list and prints out the 2d list horizontally

so say I have a 2d list like this [[' ', 'L', 'L', 'L', ' '], ['B', '.', '.', '.', 'T'], ['B', '.', '.', '.', 'T'], ['B', '.', '.', '.', 'T'], [' ', 'R', 'R', 'R', ' ']]

and when I run the function print_rec(2d_list):

I want the 2d list to be printed out to the console and display like this

TTT

L...R

L...R

L...R

BBB

and also I want a function that returns a 2d list that when the function is run build_2dlist(wid,hei)

and the function would return the list [[' ', 'L', 'L', 'L', ' '], ['B', '.', '.', '.', 'T'], ['B', '.', '.', '.', 'T'], ['B', '.', '.', '.', 'T'], [' ', 'R', 'R', 'R', ' ']]
