PLZ HURRY! Why is it important that if, elif, and else statements appear in the proper order? (coding)

If a>b:
elif belse:
And now,
if b>c:
elif a>b:
else:
Now, for the calculation, it is quite clear that long-distance has to be traveled in the second case, as compared to the first case. And hence, the second code. and which is not in the proper code is going to take more time. And the first code which is in the proper format is going to take less time. And that is why we need to have the if, elif and the else statement in the proper format.
