Any Ideas how to write a python intepretor in fuze

I know the idea is very stupid but does anyone have a idea how to do this

Writing an interpreter for any language can be quite daunting, but If you feel up to the task I'd recommend starting with a very basic subset of Python. Maybe something like if and while statements with basic mathematical expressions.
The topic of interpreter and compiler design is way to deep to explore in a single post but here is a brief overview of some of the steps and concepts involved in writing an interpreter. Hopefully it will give you an idea of what to google.
The first step would be to write a function that scans the source code and outputs a sequence of tokens where each token represents a syntactical element such as a number, a variable name, a keyword or an operator. This step is called lexical analysis and the function performing it is often called a "lexer".
The next step would be to write a function that parses the sequence of tokens and outputs an abstract syntax tree (AST for short) that is an internal data representation of the source code. This step is called syntax analysis and the function performing it is usually called a "parser". This is quite a bit harder than the first step but there are several existing methods that can be used for parsing a syntax, I recommend looking into "recursive descent" for parsing statements and "precedence climbing" for parsing expressions.
After an AST has been created you can run the program by traversing the AST and performing the operations that each tree node describes. There are other steps as well such as semantic analysis, optimization and code generation/execution, but for a very basic syntax the steps I described should be enough.
I hope this helps you get started. It is not an easy topic but once things start to click it can be very rewarding (at least if you are a geek like me:)

@sahara-min Thank you so much my brain was breaki when i was sitting in front of the fuze ide it must be a python intepreter written in fuze because i want to show how much you can do with it.Could you please say me how to define an if statement or how to let the parser it parse

I'd suggest starting with parsing expressions before parsing if-statements because parsing if-statements requires parsing expressions. Start with the simplest possible expression, a single number, and build from there.
