按題目要求，應該是這么寫吧
L = [95.5, 85, 59, 66, 72]
L2 = sorted(L,reverse=True)
print(L2[0:3])
L = [95.5, 85, 59, 66, 72]
L2 = sorted(L,reverse=True)
print(L2[0:3])

短路計算。真 and? 假 總是輸出假,所以True and 0輸出0，你也說了False和0等價，所以輸出0和輸出False等價。假 or 真 總是輸出真，是指輸出真的那個語句，如果先賦值a = False， 0 or a 則輸出False即a 的值

length =3.14
width=1.57
result=round(length*width)
print(result)
不用加變量類型和分號，簡單的有點不習慣
