使用列表推导式1.随机生成50个学生的学费，【4500,6500】，放入列表，打印 2.将学生学费改为新学费新学费=学费*0.8+568，打印 3.将学费超过6500的减少500，低于6000的增加500，打印

1. 随机生成50个学生的学费，【4500,6500】，放入列表，打印

import random

fees = [random.randint(4500, 6500) for _ in range(50)]
print(fees)

2. 将学生学费改为新学费新学费=学费*0.8+568，打印

new_fees = [(fee * 0.8 + 568) for fee in fees]
print(new_fees)

3. 将学费超过6500的减少500，低于6000的增加500，打印

modified_fees = []
for fee in new_fees:
    if fee > 6500:
        modified_fees.append(fee - 500)
    elif fee < 6000:
        modified_fees.append(fee + 500)
    else:
        modified_fees.append(fee)

print(modified_fees)
