PYTHON would result from conversion to a percentile rank system

To achieve the percentile score into a hierarchy, we must first understand the structure of a multi-branch selection

Multi-branch selection structure syntax is:

if expression 1:

    Statement block 1

elif expression 2:

    Statement block 2

elif expression 3:

    Statement block 3

...

else：

   Statement block n

Now we can enter the code:

def func(score):
    if score>100:
        return'wrong score.must<=100.'
    elif score>=90:
        return'A'
    elif score>=80:
        return'B'
    elif score>=70:
        return'C'
    elif score>=60:
        return'D'
    elif score>=0:
        return'E'
    else:
        return'wrong score.must>0'

The results are shown as follows:

 But this fancy little tedious programming, we can try another Python code to write:

code show as below:

def func(score):
    degree='DCBAAE'
    if score>100 or score<0:
        return'wrong score.must between 0 and 100'
    else:
        index=(score-60)//10
        if index>=0:
            return degree[index]
        else:
            return degree[-1]

The results are shown as follows:
