python 从键盘输入若干个整数，当输入“-1““时输入结束，请统计最大值、最小值和平均数

python 从键盘输入若干个整数，当输入"-1""时输入结束，请统计最大值、最小值和平均数

上面题目代码如下：

第一种方法列表方法求：

a=[]b = int(input())while True:    if b == -1:        break    a.append(b)    b=int(input())    if b==-1:        breakif b==-1:    print('Count is 0')    print(f'Max number is 0')    print(f'Min number is 0')    print('The average number is 0')else:    print('Count is ' + str(len(a)))    print(f'Max number is{max(a)}')    print(f'Min number is{min(a)}')    print('The average number is ' + str(sum(a) / len(a)))

第二种方法，冒泡排序算法求得

arr=[]while True:    a = int(input())    if a==-1:        break    # 遍历所有数组元素    arr.append(a)    print(type(arr))    for i in range(len(arr)):        # Last i elements are already in place        for j in range(0, len(arr) - i - 1):            if arr[j] > arr[j + 1]:                arr[j], arr[j + 1] = arr[j + 1], arr[j]if a==-1:    print('Count is 0' )    print(f'Max number is 0')    print(f'Min number is 0')    print('The average number is 0' )else:    print('Count is ' + str(len(arr)))    print(f'Max number is{arr[0]}')    print(f'Min number is{arr[-1]}')    print('The average number is ' + str(sum(arr) / len(arr)))

代码中，考虑到-1这种情况，做了如下处理：
