python：sql建表语句转换为json

标签：-- discount cat class sage int iter rtti ace

热心网友时间：2022-05-01 23:26

如果datas是Python的原始数据，并且datas中没有非ascii码，可以使用如下语句转换为json格式：
import
json
json.mps(datas)
当datas中含有中文等非ascii字符时，可以使用如下参数：
json.mps(datas,
ensure_ascii=False)
如果想美化输出格式，可以使用indent参数：
json.mps(datas,
indent=4)
