**kwargs

Now, let's move on to keyword arbitrary arguments or **kwargs. The principle of how **kwargs works is the same as for *args, but it accepts keyword arguments instead of positional ones. **kwargs packs information into a dictionary, so we will work with it accordingly.

The correct order for the arguments is as follows:

Positional
Optional
*args
**kwargs

If you want to unpack dictionaries, you need to use ** before the dictionary variable.

1. What does **kwargs in a Python function signature represent?

2. What will print_details(name="Alice", age=30) output?

3. Given the function definition below, which call is valid?

What does **kwargs in a Python function signature represent?

Selecione a resposta correta

A syntax error in Python.

A single keyword argument.

A dictionary of all keyword arguments passed to the function.

A tuple of all keyword arguments passed to the function.

What will print_details(name="Alice", age=30) output?

Selecione a resposta correta

Alice: 30

{"name": "Alice", "age": 30}

name: Alice, age: 30

Syntax error

Given the function definition below, which call is valid?

Selecione a resposta correta

mix_args(1, 2, 3, x=4, y=5)

mix_args(x=1, y=2, 3, 4)

mix_args()
