Your program has a few issues: 1. `traceback.extract_stack()` returns the current stack, not the stack at the point of the exception. 2. You should use `traceback.extract_tb()` to get the traceback from the exception. 3. `frame.locals` is not a valid attribute. You should access `frame`'s `locals` using the `frame.f_locals` attribute. 4. The caught exception should be unpacked correctly. Here's the corrected version:

I extracted the following code from that output:

Your current implementation has a few issues that need to be addressed: 1. The `traceback.extract_stack()` function captures the current stack trace, but what you need is the stack trace from the exception, which can be obtained using `traceback.extract_tb()` within the `except` block. 2. The `frame.locals` attribute doesn't exist. Instead, you need to use the `frame.f_locals` attribute from `traceback.format_stack()` or `traceback.extract_tb()`. 3. When printing the variables, you need to ensure that the values are converted to strings. Here's the corrected version of your program:

There are a few issues in the provided code: 1. `traceback.extract_stack()` should be replaced with `traceback.extract_tb()` to get the stack trace from the exception. 2. The loop to print the local variables in each stack frame is incorrect. `frame.locals` doesn't exist. Instead, you should use `frame.f_locals` to access the local variables in a frame. 3. `traceback.extract_tb()` returns a list of `FrameSummary` objects, which do not contain local variables. Instead, you need to use `traceback.format_exc()` to get the full traceback including local variables. Here's the corrected code:
