603 數字排序

list3 = []
for i in range(10):
    num = eval(input().strip())
    list3.append(num)

list3.sort()
print(list3[-1], list3[-2], list3[-3])

append函數增加數值到陣列最右邊一格, 陣列.sort 可把陣列數值由小到大排序, 再用負索引(negative index)把數值由大到小印出

703 串列數組轉換

list2 = []
num2 = int(input().strip())

while num2 != -9999:
    list2.append(num2)
    num2 = int(input().strip())

tuple2 = tuple(list2)

print(tuple2)
print("Length:",len(tuple2))
print("Max:",max(tuple2))
print("Min:",min(tuple2))
print("Sum:",sum(tuple2))

將list轉為tuple, 再用len(), max(), min(), sum()函數來做數值分析

802 字元對應

word = (input().strip())
total = 0
for i in range(len(word)):
    print("ASCII code for '%s' is %d" %(word[i], ord(word[i])))
    total += ord(word[i])
print(total)

len(字串),測出的長度做for迴圈重複的次數上限, ord()則可找出字元對應的ASCII碼
