参数start=0,指定初始默认值

"""
for item in enumerate("dfkdjf",start=10):
    print(item)
for _, item in enumerate("dfkdjf"):
    print(item)

结果：

(10, 'd')
(11, 'f')
(12, 'k')
(13, 'd')
(14, 'j')
(15, 'f')
d
f
k
d
j
f

names = ["tom", "mary", "jerry"]
address = ["北京南区", "北京西区"]
res = zip(names, address)
for item in res:
    print(item)
