Python-查找两个文件中相同的ip地址

with open("testt","r") as f1:
    list1 = f1.readlines()
    print(list1)
list1 = set(list1)

with open("test2","r") as f2:
    list2 = f2.readlines()
    print(list2)
list2 = set(list2)

same_data = list1.intersection(list2)
print(same_data)

for i in same_data:
    print(i.strip())
