“列表索引超出范围”仍然出现错误

Question

basically i'm trying to find whether or not a list has the '007' in them. the output still spits out what i'm looking for but at the end i'm still getting "list index out of range" error. C&P jupyter and see for yourself. i know it has something to do with the huge ass if statement but i just dont see the issue, i'm basically just looking for '007' which if it doesn't it'd just skip its logic... is it my code or is it jupyter acting crazy?

def spy_game(nums):
    listy = []

    for x in nums:
        if x == 0 or x == 7:
            listy.append(x)

    print(listy)
    #compare listy indexes
    for x, y in enumerate(listy):
        if y == 0 and listy[x + 1] == 0 and listy[x + 2] == 7:
            print(True)
            break
        elif y == 7:
            print(False)

spy_game([1, 2, 4, 0, 0, 7, 5])
spy_game([1, 0, 2, 4, 0, 5, 7])
spy_game([1, 7, 2, 0, 4, 5, 0])

Answer 1

L = [1, 2, 4, 0, 0, 7, 5]

if "007" in "".join([str(x) for x in L]):
     # There is a 007 in the list
