Python on Android

If I managed to carry out a designated task via code on a .py file, how can I use either Java/Kotlin to interact with the .py file,

Assuming, I carried out a task using numpy and pandas, everything workes well via a python compiler and the expected results are achieved. If I want to make and Android app, which does the same task, how would I be able to achieve that.

Im using the following:
1. Anaconda
2. Eclipse for Android development

I currently don't have knowledge on Kivy and Django so I'm not using that
