Will the data files be lost when I update my game apk in play store?

First things first, I’m very new to devloping android applications and games, so please bare with my poor knowledge of things. Thanks!

So I’m developing a game in kivy, where the data such as money, items, level are started in a seperate py file. Essentially, there is a main.py and a data.py. Now if/when I update my game on play store, will it lose the data.py, causing it to reset everything? If yes, how should I overcome it? Thanks a ton in advance!

Answer

If I understand correctly you are storing the data in a python file? I would recommend against this, and would instead suggest you store the data in something like a json or CSV. The python file will be overwritten if you update the app, however if you use a file saved externally on the device it will not.
