要将Python中的对象转换成JSON字符串,可以使用json.dumps()方法。该方法接受一个Python对象作为参数,并返回一个JSON格式的字符串。
例如,假设我们有一个字典对象dict01,包含"name"、"gender"和"age"等键值对,我们可以使用json.dumps()方法将其转换成JSON字符串。代码示例如下:
import json
dict01 = {
"name": "jack",
"gender": "boy",
"age": "25"
}
json_string = json.dumps(dict01)
print(json_string, type(json_string))
输出结果为:
{"name": "jack", "gender": "boy", "age": "25"} <class 'str'>
这样,我们就可以得到一个JSON格式的字符串json_string,其中包含了字典对象dict01的所有键值对。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
