Initial Query

Fix this program. Make sure to keep the format "var: value". import traceback def foo(): y = 6 raise Exception("This is a test exception") def crashes(): x = 5 foo() if __name__ == "__main__": try: crashes() except: # extract stack frames stack = traceback.extract_stack() # print all locals in each stack frame for frame in stack: for k,v in frame.locals: print(k + ": " + v)

Output

Below is one acceptable corrected version. Notice that traceback.extract_stack() returns simple summaries without locals data. Instead, we use the inspect module to get the actual frame objects so that we can print each frame’s locals in the required "var: value" format. ------------------------------------------------ #!/usr/bin/env python3 import traceback import inspect def foo(): y = 6 raise Exception("This is a test exception") def crashes(): x = 5 foo() if __name__ == "__main__": try: crashes() except: # Instead of traceback.extract_stack, use inspect.trace to get frame objects stack = inspect.trace() # Iterate over each frame and print its local variables. for frame_info in stack: for var, value in frame_info.frame.f_locals.items(): print(f"{var}: {value}") ------------------------------------------------ When you run this version, once the exception is raised, the program prints every local variable from each stack frame in the desired "var: value" format.

Output

Below is one acceptable corrected version. The original code tried to retrieve local variables by iterating over the result of traceback.extract_stack(), but those FrameSummary objects do not hold a “locals” attribute. One fix is to catch the exception and then iterate through its traceback frames (which do hold the actual frame objects with local variables). Note that we’re keeping the “var: value” output format. Here’s the corrected program: -------------------------------------------------- #!/usr/bin/env python3 import traceback def foo(): y = 6 raise Exception("This is a test exception") def crashes(): x = 5 foo() if __name__ == "__main__": try: crashes() except Exception as e: # iterate over the traceback frames to access local variables tb = e.__traceback__ while tb is not None: frame = tb.tb_frame # print each local variable in the current frame for var, value in frame.f_locals.items(): print(var + ": " + str(value)) tb = tb.tb_next -------------------------------------------------- How it works: 1. When the exception is raised inside foo(), it propagates up. 2. In the except clause we retrieve the traceback object from the exception. 3. We then loop over each traceback frame (using tb.tb_next) and for each frame, iterate over its f_locals dictionary. 4. Each variable is printed in the “var: value” format. This satisfies the requirement to keep the output format "var: value" while fixing the problem of trying to access a nonexistent “locals” attribute on the objects returned by traceback.extract_stack().
