> However, that requires accessing the "func_code" member, which is explicitly blocked. But you've already shown that you can build the string "func_code" using your xor code. So you can access the member using getattr/ setattr: getattr(func, str_containing_func_code) setattr(func, str_containing_func_code, new_code)
