frame type in python

Question

In a python reference manual said that

A code block is executed in an execution frame. A frame contains some administrative information (used for debugging) and determines where and how execution continues after the code block’s execution has completed.

and

Frame objects represent execution frames. They may occur in traceback objects

But I don't understanf how frame does work. How can I get an acces to a current frame object? When is frame object creating? Is the frame object created everytime when a code of new block is strarting to execute?

Answer 1

These frames are representations of the stack frames created by function calls. You should not need to access them in normal programming. A new frame is indeed created every time a function is called, and destroyed when it exits or raises an uncaught exception. Since function calls can go many levels deep your program ends up with a bunch of nested stack frames, but it's not good programming practice (unless you are writing a debugger or similar application) to mess about with the frames even though Python does make them available.
