info = {"key_1": "value_1", "key_2": "value_2", "key_3": {"key_4": "value_4", "key_5": "value_5"}}
with open("a.json", "w") as f:
    f.write(json.dumps(info, ensure_ascii=False, indent=4, separators=(',', ':')))

　　

读取json文件：

with open('./a.json', 'r', encoding = 'utf8') as fp:
    json_data = json.load(fp)
