So, first I need a parse building tool, I don’t know exactly what it is and where I think, if possible preferably in the Python language.
I will use this tool in order to implement an expression recognizer for a "recursive descending parser" that I created earlier.

What you want is a generator parser and probably the ANTLR is the most used of all. Not that it is certainly the best for what it needs. Coco/R is another well used. Another is the Sablecc. Some like the Javacc. Some people still prefer the old YACC/Bison. It’s worth taking a look at GOLD. Not everyone generates Pyhton code.
To know how you do the parser just enter a course with a good workload on the subject, can not answer in a reply on the internet, mainly in an exact way.

For Python my favorite is the Lark-parser https://github.com/lark-parser/lark (Pip install Lark-parser).
