如何在字典列表中打印字典值？

Question

我有一个字典列表，我想从每个字典中打印某些键：

dict_results=[{'terms':['hi','bye'],'title':'01234def','text':'hello, how are you?'},{'terms':...}...]

这不起作用：

for item in dict_results:
    print "{0},{1}".format(item[0]['title'],item[0]['text'])

键错误：0

Answer 1

循环浏览list，然后访问每个词典的键：

>>> dict_results=[{'terms':['hi','bye'],'title':'01234def','text':'hello, how are you?'},
...               {'terms':0, 'title':'hello', 'text':'world'}]
>>> for d in dict_results:
...     print(d['title'], d['text'])
...
01234def hello, how are you?
hello world

Answer 2

dict_results=[{'terms':['hi','bye'],'title':'01234def','text':'hello, how are you?'}]

for item in dict_results:

    print("{} {} {}".format(item['terms'], item['title'],item['text']))

    ['hi', 'bye'] 01234def hello, how are you?
