遍歷字典值

1. 使用 items() 可以遍歷 (traverse) 字典的鍵及值，若只想遍歷字典的值，可用如下 values()：

   for value in dict_name.values():
   

2. 範例：遍歷並列出字典 uid 的值。

   [dywang@deyu zzz]$ cat dict8.py
   #!/usr/bin/python3
   # coding: utf-8
   
   uid = { 'dywang':1000, 'david':2346, 'linda':1324 }
   for value in uid.values():
   	print("uid = %d" % value)
   

3. 執行結果

   [dywang@deyu zzz]$ ./dict8.py
   uid = 1000
   uid = 2346
   uid = 1324
