implementations – Since cpython helps to implement and execute python code, should I first learn cpython?

I met this question when I came across the following answer to my question about cpython

Ans: – "Python" is a concept. This is an idea for a programming language. Of course, it's more than an idea, it's a fully developed specification of a programming language. However, as long as there is no program capable of reading a .py file and executing the code, it is only a concept.

For a .py file to be useful, it must be processed by a program that includes the language and is able to convert it to the language of the underlying machine.

When a person or team writes a program that can process a file written in Python language (for example, python.exe, / usr / local / bin / python, etc.), this program becomes an implementation of the language.
