Python：我需要一些关于以下程序的建议

Question

list1 = ["experience","as","a","java","developer"] 
list2 = ["B","O","O","B","I"] 
list3 = ["java","developer"]
number = 0
print(list2)
for i in list1:
    for j in list3:
        if(i!=j):
            for l in range(number,len(list2)):
                list2[number] = "O"
                number += 1       
print(list2)

此处"B"表示＆＃34;经验＆＃34;，"O"代表＆＃34; as＆＃34;等等。

预期产出：

["O","O","O","B","I"]

我的输出：

["O","O","O","O","O"]

Answer 1

如果我理解你的问题是正确的，你需要这样做：

for i in range(len(list1)):
    if list1[i] not in list3:
        list2[i] = "O"

print(list2)

输出[＆＃39; 0＆＃39;，＆＃39; 0＆＃39;，＆＃39; 0＆＃39;，＆＃39; B＆＃39;，＆＃39;我＆＃39;]
