How to use firebase_admin Python?

Python

How to use firebase_admin ? There is almost nothing on the Russian-language forums for the fresh library for working with firebase in python. After reading a piece of documentation on the official website, I didn’t understand at all what was needed for what. There is a lot of information, it is all in English and I don’t understand what is needed for ... Who figured it out, please explain:
1) How to load data into a database table, change or delete (with realtime database)
2) How to encrypt sent data, and decrypt the received ones (maybe there is a separate library for this, for example, which encrypts by key and length, like a hash function?)
3) How to store picturesto firebase and load them from there (with python)?
PLEASE GIVE AN EXAMPLE OF CODE WITH COMMENTS!!!
