Check the two special cases, and let else catch the last one.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, compare your working with the solution.
Plan. Again three cases.
if n > 0:showspositive.elif n < 0:showsnegative.else:the number must be0, so it showszero.
Check. For it shows negative. For it shows zero.
