json文件为空时读取会报错
simplejson.errors.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
提示说是解码错误
可以用下面的方法判断json文件是否为空
import json
#读取 with open('tmp.json', 'r') as f: data = f.read() if(not bool(data)): print("json is empty!")
但是在非空情况下会报错!!!
import json data ={"vf":"ff"}
#写入 with open('tmp.json', 'w') as f: json.dump(data, f) #读取 with open('tmp.json', 'r') as f: data = f.read() print(data)
#判断 if(not bool(data)): print("json is empty!")
