   Nov 3, 2019 · Python/compile.c::PyAST_CompileObject compiles AST node to code object. First, Python/symtable.c::PySymtable_BuildObject builds a symbol table from the AST. The symbol table stores the scope type of each name symbol in each code block. Then Python/compile.c::compiler_mod visits each node in the AST to emit bytecode, and creates a code object in ...

   The conversion process is initiated by a call to the function _PyAST_Compile() in Python/compile.c. This function does both the conversion of the AST to a CFG and outputting final bytecode from the CFG.

   What is a Python code object?

   • It is not that commonly used. It is used when you have Python source code in string form, and you want to make it into a Python code object that you can keep and use. Here's a trivial example: Basically, the code object converts a string into an object that you can later call exec on to run the source code in the string.

   How do I manipulate code objects in Python?

   • So something to manipulate code objects would need to interface with the respective Python C API. This concludes a rather short tour of parsing and a very long tour of bytecodes. One major take back to this is that bytecode related functionality will be dependent upon the Python implementation and version being used.

   How to convert AST to Python bytecode?

   • The first step is to convert the AST to Python bytecode without having jump targets resolved to specific offsets (this is calculated when the CFG goes to final bytecode). Essentially, this transforms the AST into Python bytecode with control flow represented by the edges of the CFG. Conversion is done in two passes.

   Why do we use Exec and compile in Python?

   • For instance, if you have a Python program that allows users to script its behavior with custom Python code, you might use compile and exec to store and execute these user-defined scripts. Another reason compile is rarely used is that, like exec, eval, and their ilk, compile is a potential security hole.

   What is pyparser_astfromnodeobject?

   • In the end it calls PyParser_ASTFromNodeObject that will be final step of the parsing, the AST is the Abstract Syntax Tree, you can also have access to this part from the python code, this is an amazing meta-programming technique for Python programs, it’s also similar to other implementations, such as Julia and LUA.
