獲取從字典

Question

關鍵

我剛開始使用Python，

是否有字典一些迭代像PHP

foreach(aData as key=>value) 

Answer 1

看起來是這樣的：

my_dict = {"key1": 1, "key2":2} 
my_dict.items()  # in python < 3 , you should use iteritems() 
>>> ("key1", 1), ("key2", 2) 

這樣你就可以迭代：

for key, value in my_dict.items(): 
    do_the_stuff(key, value) 

Answer 2

用途：

for key in dictionary.keys() 
    value = dictionary[key] 
    #do something 

OR：

for key,value in dictionary.items(): 
    #do something 

Answer 3

假設蟒2：

for key, value in aData.iteritems():
