Question

Python这个代码错在哪？

import jsonfilename = 'username.json'try: with open(filename)as f_obj: username = json.load(f_obj)except FileNotFoundError: username = input("what's your name?:") with open(filename,'w')as f_obj: json.dump(username,f_obj) print("We'll remember you when you comeback, "+username+"!")else: print("Welcome back, "+username +' !')明明书上说是可以运行的代码 但是却返回了一大串的错误代码

Answer 1

username.json这个文件里面存的不是json格式的数据

Answer 2

load()函数中的json格式有问题，建议题主去看看
