python 读空的json文件

 

读空的json文件，python2和python3 的错误提示是不一样的

python2:

ValueError: No JSON object could be decoded

python3:

json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

 

解决：

针对python2

import json data ={"vf":"ff"} ''' #写入 with open('tmp.json', 'w') as f: json.dump(data, f) ''' try: with open('tmp.json', 'r') as f: k=json.load(f) print(k) except ValueError:　　print("empty!")

针对python3

import json data ={"vf":"ff"} ''' #写入 with open('tmp.json', 'w') as f: json.dump(data, f) ''' try: with open('tmp.json', 'r') as f: k=json.load(f) print(k) except json.decoder.JSONDecodeError: print("empty!")
