Python编辑查询成绩

方法一:

n =int(input('请您输入成绩查询分数:'))

if int(n) >=90:

        print('优秀')

elif int(n) >=80:

        print('好')

elif int(n) >=70:

        print('良')

elif int(n) >=60:

        print('及格')

else:

        print('你要努力了')

if n>=90:

        print('优秀')

elif n>=80:

        print('好')

elif n>=70:

        print('良')

elif n>=60:

        print('及格')

else:

        print('你要努力了')

方法二:(优化)

n =int(input('请您输入成绩查询分数:'))

if n>=60 and n<70:

        print('及格')

elif 70<=n<80:

        print('良')

elif 80<=n<90:

        print('好')

elif n>=90:

        print('优秀')

else:

        print('你要努力了!!!')
