python循环字典的两种方式

import sys,os

a={"package_server1_url":"/mountpath/server1/path",
   "package_server1_mount_cmd":"mout 172.*.*.*/server1 /mountpath/server1/path",
   "package_server2_url":"/mountpath/server2/path",
   "package_server2_mount_cmd":"mout 172.*.*.*/server1 /mountpath/server2/path",
   "package_server3_url":"/mountpath/server3/path",
   "package_server3_mount_cmd":"mout 172.*.*.*/server3 /mountpath/server3/path",
   "package_server3_eg":"aaaaa",
   "package_server4_url":"/mountpath/server4/path",
   "package_server4_mount_cmd":"mout 172.*.*.*/server4 /mountpath/server4/path"
   }
#第一种循环：直接items循环
for i,j in a.items():
    print(i+"*********"+j)

#第二种循环：通过key值
for k in a:
    print(k+"#########"+a[k])

结果是一样的
