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

To fix this program, we need to correctly capture and print the local variables from each stack frame when an exception occurs. The key issue is accessing the actual traceback of the exception to retrieve local variables from each frame. **Step-by-step explanation:** 1. Use `sys.exc_info()` to get the exception's traceback. 2. Traverse the traceback frames to access each frame's local variables using `f_locals`. 3. Properly format variable values as strings to avoid type errors.

            print()  # Add a newline for separation
            tb = tb.tb_next

Check if all of the following conditions are true:

Substring Evaluation

Testing if the previous output contains the string y: 6: False

Substring Evaluation

Testing if the previous output contains the string x: 5: False

Final Answer: False
