我需要帮助使用python来处理JSON格式的数据

Question

我是新来的。我的代码出了点问题。

我有如下格式的JSON：

[{"word":"ingenious","score":1828,"numSyllables":3}, 
{"word":"heterogeneous","score":1139,"numSyllables":5}]

我想使用python对每个键进行迭代，然后获取值并打印它，这样每个单词就在一个新的行上，nymSyllables放在它旁边的括号中。预期结果如下：

ingenious (3)
heterogeneous (5)

Answer 1

只需循环遍历列表中的对象，并为每个对象打印所需的字符串：

arr = [{"word":"ingenious","score":1828,"numSyllables":3}, 
{"word":"heterogeneous","score":1139,"numSyllables":5}]

for obj in arr:
    print('{} ({})'.format(obj['word'], obj['numSyllables']))

输出：

ingenious (3)
heterogeneous (5)

如果您想这样做，也可以在一行中这样做：

print('\n'.join('{} ({})'.format(obj['word'], obj['numSyllables']) for obj in arr))

输出：

ingenious (3)
heterogeneous (5)
