for…in()

只能遍历列表中的元素，不会获得索引值

list = ["星期一", "星期二", "星期三", "星期四", "星期五", "星期六", "星期日"]
for  item in list:
    print(item)

enumerate()用法

既遍历索引，又遍历元素

list = ["星期一", "星期二", "星期三", "星期四", "星期五", "星期六", "星期日"]
for index, item in enumerate(list):
    print(index, item)

for…in zip()

并行遍历列表

s = ["1", "2", "3", "4", "5"]
t = ["a", "b", "c", "d", "e"]

for x, y in zip(s, t):
    print(x+"-"+y)

for…in range()

for i in range(10):
    print(i)
