Answer from AI
Using **kwargs in Python is recommended in the following cases:
- When you need to accept an arbitrary number of named arguments that are unknown in advance.
- To create functions with a flexible interface that allows extending functionality without changing the signature.
- When wrapping or decorating functions to pass all named parameters further.
Example:
def log_event(event_type, **kwargs):
print(f"Event: {event_type}")
for key, value in kwargs.items():
print(f"{key}: {value}")
log_event("user_logged_in", user_id=123, ip="192.168.1.1")
This approach makes it convenient to work with additional parameters without limiting the number and names of arguments.
