Migration from Juniper SRX firewall to PaloAlto using python

My Python program is open source. You can read, use, update, add your own functions.
The program converts structured text to another structured text and is under development.
To understand this program, you need to know the basic operations in Python, text, list, and dictionary.
I am writing this text for network engineers who are learning Python, I want to show you the direction of development.
I have added as many comments as possible to the text for better understanding.
Both Juniper Firewall and PaloAlto use address objects (set address) and address group objects (set address-group).
In both firewalls, address objects are used as source IP addresses or destination IP addresses in policies or rules.
Here we see address objects (set address). On the left is Juniper, on the right are the same objects converted to PaloAlto.

The program reads the Juniper configuration text and looks for the words "set security address-book global address",
then the program finds the object name and object prefix.

Here we see address group objects (set address-group). On the left is Juniper, on the right converted to PaloAlto.
In Juniper, the address-set can consist of several objects in several lines, in PaloAlto in one line several objects in square brackets.

And then python converts "security policies global", as it is called in SRX, to "rulebase security rules" in PaloAlto.
For simplicity, I use "global security policies", which means that it is not related to any zone,
it applies from any zone to any zone.
