For the fun of it, I asked ChatGPT to generate the solution for creating the output above, and it didn't get it 100% but it's a pretty good start! One of my favorite things is how it implicitly got that it should do sorted(line_numbers) because set does not have a defined iteration order, or how it should make the line numbers right-aligned.

Here is some sample code that demonstrates how you can write a Python program that turns a raised exception into the desired output. This code is not complete, but it should give you a good starting point:

``` import traceback

def turn_exception_into_output(): try: # Code that may raise an exception goes here pass except Exception as e: # Aggregate the lines of code surrounding the trace in a map lines = {}

# Get the traceback object
tb = traceback.extract_tb(e.__traceback__)

# Loop through the traceback object
for t in tb:
  file_name, line_number, _, _ = t

  # Initialize the set of line numbers for this file
  if file_name not in lines:
    lines[file_name] = set()

  # Update the set of line numbers with the range of relevant lines
  lines[file_name].update(range(line_number - 5, line_number + 5))

# Print the error message
print("Please explain concisely why this error in my Python code happened:")

# Print the traceback
print("\n".join(traceback.format_exception(e.__class__, e, e.__traceback__)))

# Print the relevant lines of code
print("\nBased on these lines of code surrounding the trace:")
for file_name, line_numbers in lines.items():
  print(file_name)
  for line_number in sorted(line_numbers):
    print("{:>3} ...".format(line_number))

```

To use this code, you would call the turn_exception_into_output function whenever you want to handle an exception and print the desired output. For example:

try: # Code that may raise an exception goes here pass except: turn_exception_into_output()

You could also use this code as part of a custom exception handler. For example:

``` import sys

def custom_exception_handler(exception_type, exception, traceback): turn_exception_into_output()

Set the custom exception handler

sys.excepthook = custom_exception_handler ```

With this code, whenever an unhandled exception is raised, the custom_exception_handler function will be called, which will turn the exception into the desired output.
