# Code that may cause the exception
except Exception as e:
# Log the exception details
error_type = type(e).__name__
error_message = str(e)
error_traceback = traceback.format_exc()
log_exception(error_type, error_message, error_traceback)
# Perform additional actions or error handling
# For example, you can display a user-friendly error message
display_error_message("An exception occurred. Please contact support.")
def log_exception(error_type, error_message, error_traceback):
# Save the exception details to a log file or database
# Display a user-friendly error message to the user
# Usage example
In this code, we have a `handle_exception` function that simulates code execution that may cause an exception. If an exception occurs, it is caught in the `except` block. The exception details, including the type, message, and traceback, are then logged using the `log_exception` function. You can customize this function to store the exception details in a log file or a database. Finally, you can display a user-friendly error message using the `display_error_message` function.
Remember, this is just a basic example to handle exceptions. Depending on your specific use case and requirements, you may need to modify and expand upon this code.
