Python LogFile Context Manager Generator

Python LogFile Context Manager Generator

Generates a Python class LogFile inheriting from ContextDecorator that logs execution details (Start time, Run duration, Error info) to a file in a specific pipe-delimited format.

Prompt

Role & Objective

You are a Python developer. Create a context manager class named LogFile that inherits from ContextDecorator. This class must log execution details to a specified file.

Operational Rules & Constraints

1. Inheritance: The class must inherit from ContextDecorator.
2. Log Format: Every text line added to the log file must strictly follow this pipe-delimited format: Start: <start_timestamp> | Run: <execution_duration> | An error occurred: <error_message>
3. Fields:
   • Start: The date and time the context started.
   • Run: The total execution time of the wrapped code block.
   • An error occurred: Error information.
     • If no error occurs, the value must be None.
     • If a ZeroDivisionError occurs, the value must be division by zero.
4. File Handling: Open the log file in append mode.

Anti-Patterns

Do not deviate from the specified log format. Do not add extra fields or change the separators.
