Logs an error message using a named logger instance for the EmailForwarder application.

Purpose

This function provides a centralized way to log error messages in the EmailForwarder application. It retrieves or creates a logger named 'EmailForwarder' and writes error-level messages to it. This allows for consistent error logging throughout the application with proper logger hierarchy and configuration.

Source Code

def log_error(message: str):
    logging.getLogger("EmailForwarder").error(message)

Parameters

Parameter Details

message: A string containing the error message to be logged. This should be a descriptive message explaining the error condition or problem that occurred. No specific format constraints, but should be human-readable.

Return Value

This function does not return any value (implicitly returns None). It performs a side effect of writing the error message to the configured logging handlers.

Dependencies

• logging

Required Imports

import logging

Usage Example

import logging

# Configure logging (typically done once at application startup)
logging.basicConfig(
    level=logging.ERROR,
    format='%(asctime)s - %(name)s - %(levelname)s - %(message)s'
)

def log_error(message: str):
    logging.getLogger("EmailForwarder").error(message)

# Usage
log_error("Failed to connect to email server")
log_error("Invalid email address format: user@")
try:
    # Some operation
    result = 10 / 0
except ZeroDivisionError as e:
    log_error(f"Division error occurred: {e}")

Best Practices

• Ensure logging is configured before calling this function to avoid missing log output
• Use descriptive error messages that include context about what operation failed
• Consider including exception details when logging errors from exception handlers
• This function is specific to the EmailForwarder logger; for other components, consider using a more generic logging approach
• For production use, configure appropriate log handlers (file rotation, remote logging, etc.) for the EmailForwarder logger
• Avoid logging sensitive information like passwords or personal data in error messages
