方式一:
<!-- lang: python -->
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:
<!-- lang: python -->
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()
<!-- lang: python -->
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()
<!-- lang: python -->
app_list = [1234, 5677, 8899]
<!-- lang: python -->
for app_id in iter(app_list):
<!-- lang: python -->
print app_id
输出: 1234 5677 8899
