I did a while loop in for loop, but I kept getting time out...

Probably because your code returns a wrong answer. If the only thing you did was replacing print with return, then your code only returns a part of the whole string.

When I use return Instead it is still saying I failed the tests

If all tests fail with some message similar to Expected 'Something' but got None or something along those lines (depending on language and assertions library used), it might mean that you are printing your answer to standard output instead of returning it from your function. This problem occurs especially often for people who do not understand the difference between printing a value and returning it, or when someone comes from some other competitive programming website which actually requires values to be printed and not returned.

You're printing the result to the console instead of returning it.

test.assert_equals(draw_stairs(3), stairs)
                        ^
#           Your function is returning None                    

Still dont know why

Why does this Code linked to this not Work as a solution I got the same output as displayed

I wrote a code that gives me the same result as the output in the instructions, but it keeps giving me errors when I test it on the code compiler.

Why is this particular exercise in 8 kyu? Definitely not an "easiest" coding problem. I think of easiest as very beginner type of functions and 7 kyu as stretching the easiest to figure out to include an extra step or two.
