How can you pass a variable number of keyword arguments to a function in Python?

Solution (By Examveda Team)

Correct Answer: A) By using the **kwargs syntax

Keyword Arguments: In Python, keyword arguments are arguments passed to a function along with a name (the keyword) and a value.

Example: my_function(name="Alice", age=30)

Variable Number of Keyword Arguments: Sometimes, you don't know in advance how many keyword arguments a function might receive. That's where **kwargs comes in.

kwargs Explained:

* The **kwargs syntax allows a function to accept any number of keyword arguments.

* kwargs is just a name (you could technically use another name), but ** is what's important. It tells Python to collect all the keyword arguments into a dictionary.

* Inside the function, kwargs acts like a regular dictionary where the keys are the argument names (like "name" and "age") and the values are the corresponding argument values (like "Alice" and 30).

Why the other options are incorrect:

* Option B (*args): Used to pass a variable number of positional arguments. It collects them into a tuple, not a dictionary.

* Option C (* symbol): Used for other purposes such as unpacking iterables or enforcing keyword-only arguments, but not for passing keyword arguments.

* Option D (... symbol): The ellipsis has special meanings like use in type hints or as a placeholder, but is not related to passing arguments to functions.

Therefore, the correct answer is Option A: By using the **kwargs syntax.
