Python List数据的遍历

方式一:


app_list = [1234, 5677, 8899]
<!-- lang: python -->
for app_id in app_list:
<!-- lang: python -->
    print app_id

输出:
1234
5677
8899

方式二:


app_list = [1234, 5677, 8899]
<!-- lang: python -->
for index,app_id in enumerate(app_list):
<!-- lang: python -->
    print index, app_id

输出:
0 1234
1 5677
2 8899

方式三: 使用range()或xrange()


 app_list = [1234, 5677, 8899]
<!-- lang: python -->
    for i in range(len(app_list)):
<!-- lang: python -->
          print i,app_list[i]

输出:
0 1234
1 5677
2 8899

方式四: 使用iter()


app_list = [1234, 5677, 8899]
<!-- lang: python -->
for app_id in iter(app_list):
<!-- lang: python -->
    print app_id

输出:
1234
5677
8899
