I Am built The Interpreter Of This Programming Language To Write The Program Using Own Syntax, And I Want To Build A REPL Like Shell For To Run Command Without Depending On Other Executable File. And Very Challanging To Add Custom Syntax On CPython Source Code Rather Then Creating New Interpreter in C++ From Scratch! In Future I Will Be Add New Custom Syntax On This If I Want To Write A Executeable Program Using New Syntax To Add Easily.

Which Challenge I Faced Mostly:

•  Implement The Parser Logic For Keep Capable With Lexer Implemented By Me
•  Implement Logic To Get All Logic Of Statement/Function Definition Without Ending The Statement/Function Defination
•  Implement Syntax Validation Of Imported All Modules On Program Files
