Question

我想从“ td”中提取“ words”字段并将其显示在一行中。如何使用Python达到此效果？谢谢。

td = {'words_result': [{'words': 'a/b/c'},
                      {'words': '/c/b/a'},
                      {'words': '/1/2/3'},
                      {'words': '/3/2/1'}]}

Expectant_effect ='a/b/c/c/b/a/1/2/3/3/2/1'

Answer 1

从代码看来，这似乎是字典，而不是JSON字符串。所以我在这里有两种方式

如果只是字典- easy peasy

for i in td['words_list']:
    print(i, end='')

如果它实际上是JSON字符串-只需再导入一次

import json

jsonString = '{"words_result": [{"words": "a/b/b"}, {"words": "/d/b/a"}, {"words": "1/2/3"}, {"words": "/3/2/1"}]}'
dictString = json.loads(jsonString)

# now same as above
for i in dictString ['words_list']:
    print(i, end='')

Answer 2

您可以使用该代码：

res = []
words_result = td.get('words_result')
for words_dict in words_result:
    res.append(words_dict.get('words'))
result = ''.join(res)

print(Expectant_effect == result)

td = {'words_result': [{'words': 'a/b/c'},
                      {'words': '/c/b/a'},
                      {'words': '/1/2/3'},
                      {'words': '/3/2/1'}]}
line = '' 
for item in td['words_result']: 
            line+= item['words']                  
#Get YOUR RESULT
print(line)

JSON包含一个列表，我想拼接列表中字段的值
