python list遍历

使用enumerate()

d = [1,2,3,4,5,6,7]
for index,app_id in enumerate(d):
    print (index, app_id)

---

直接遍历

d = [1,2,3,4,5,6,7]
for index in d:
    print (index)

使用range()

app_list = [1234, 5677, 8899,77,333,112]
for i in range(len(app_list)):
    print (app_list[i])

使用iter()

app_list = [1234, 5677, 8899,77,333,112]
for i in iter(app_list):
    print (i)
