Python AttributeError: partially initialized module 'json' has no attribute 'dumps'

Python文件運行遇到一個問題:

File “J:\Python文件\python入門\week5\json\json.py”, line 3, in
s = json.dumps(dic)
AttributeError: partially initialized module ‘json’ has no attribute ‘dumps’ (most likely due to a circular import)

文件名叫做json.py,並且在上面import json,Python沒有導入模塊,自己調用了自己,報錯.
解決方法:重命名文件
