OS

import os
file_path = "E:/tt/aa/abc.py"
filepath,fullflname = os.path.split(file_path)
# filepath='E:/tt/aa'
# fullflname='abc.py'
fname,ext = os.path.splitext(fullflname)
# fname = "abc"
# ext = ".py"
# 返回指定路径下的文件和文件夹列表。
os.listdir(dir_path)

json

import json
with open("文件名") as f:
     result=json.load(f)
with open("文件名") as f:
    line=f.read():  
    result=json.loads(line)

简单来讲：load对应文件，loads对应字符串
