+## [Custom Python Interpreters​](https://docs.python.org/3/library/custominterp.html)
+
+> The modules described in this chapter allow writing interfaces similar to Python’s interactive interpreter. If you want a Python interpreter that supports some special feature in addition to the Python language, you should look at the code module. (The codeop module is lower-level, used to support compiling a possibly-incomplete chunk of Python code.)
