Python：我需要以下程序的一些建议

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)

这里的"B"表示“经验”， "O"表示“ as”，依此类推。

预期产量：

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

我的输出：

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

Answer 1

如果我正确理解了您的问题，则需要执行以下操作：

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

print(list2)

输出['0'，'0'，'0'，'B'，'I']
