python json字符串转json对象

要在Python中将JSON字符串转换为JSON对象，可以使用json模块的loads()函数。以下是一个示例代码：

import json

json_str = '{"name":"blue","age":"20"}'
json_obj = json.loads(json_str)

print(json_obj)
print(json_obj['name'])
print(json_obj['age'])

这段代码首先导入了json模块，然后使用loads()函数将JSON字符串转换为JSON对象。然后，可以像操作字典一样，通过键访问JSON对象中的值。在这个例子中，我们打印了整个JSON对象以及"name"和"age"字段的值。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
