Data reference between files

For example, at A.py I'm going to continue scrolling through the web with a repetitive phrase Store the data in a dictionary variable (the data in the variable continues to be updated).)

B.py is programming using the data, but it is difficult to read the value of the variable.

Instead of using other DBs, I want to share variable values between files in B file.

It's hard to study. Please help me.
