python for循环和列表

如何同时在for循环中使用两个列表

list1 = [1,2,3]
list2 = [3,1,2]
for q,w in list1,list2:
    print(q+w)
#报错为too many values to unpack (expected 2)

list1 = [1,2,3]
list2 = [3,1,2]
for q,w in zip (list1,list2):
    print(q+w)

list1 = [1,2,3]
list2 = [3,1,2]
for i in range(len(list1):
    print(list1[i]+list2[i])
