To obtain detailed information about an error and its environment during program execution, you can use the following approaches:

  • Logging with levels: Use logging with levels (DEBUG, INFO, ERROR) to record the program's state, variable values, and traces.

  • Exception handling with stack trace: In try-except blocks, output or save the call stack (stack trace) to understand exactly where the error occurred.

  • Using debuggers: Debugging tools (e.g., pdb for Python) allow step-by-step execution of the program and viewing variable states.

  • Gathering context: Record additional information — function parameters, environment state, configurations, execution time.

  • Monitoring and tracing: In production environments, monitoring systems (e.g., Sentry, ELK stack) are used to automatically collect and analyze errors.

Example in Python for outputting detailed error information:

import traceback

try:
    # code that may cause an error
    result = 10 / 0
except Exception as e:
    print(f"Error: {e}")
    print("Stack trace:")
    traceback.print_exc()

This will show the exact location and cause of the error.
