死囚犯枪决问题——python实现

问题：

假如有100名犯人，现在报数为奇数的枪毙，偶数的存活，请问，最后第几名犯人可以存活？...

代码：

l = [i  for i in range(1,101)]


while len(l) > 1:
    for i in l:
        if l.index(i) % 2 == 0:
            l[l.index(i)] = 0
    for each in l:
        if each == 0:
            l.remove(each)

    print(l)

结果：

[2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, 98, 100]
[4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68, 72, 76, 80, 84, 88, 92, 96, 100]
[8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96]
[16, 32, 48, 64, 80, 96]
[32, 64, 96]
[64]
