in python, don't use built in functions

Create a function powers_table that will take a number as an argument and run through the powers, but print the rows in descending order. The spacing between the numbers in each row of the output is a tab. For example powers_table(5) provides the values below 5 25 125 625 3125 4 16 64 256 1024 39 27 81 243 2 4 8 16 32 1 1 1 1 1 1 1 & But powers_table(4) provides) 4 16 64 256 3 9 27 81 2 4 8 16 1 1 1 1
