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
