What Python feature allows functions to accept an arbitrary number of positional arguments?

• A. Varargs
• B. Args
• C. Keyword arguments
• D. Default parameters

Answer: (A)

The feature that allows functions in Python to accept an arbitrary number of positional arguments is commonly referred to as "args." This is achieved by using an asterisk (*) before a parameter name in the function definition. When this syntax is used, it allows the function to capture all extra positional arguments passed to it as a tuple. For instance, if you define a function like this: ```python def example_function(*args): for arg in args: print(arg) ``` You can call this function with multiple arguments, and it will print each one: ```python example_function(1, 2, 3, 'hello') ``` This will output: ``` 1 2 3 hello ``` The term "args" is a conventional name given to this parameter, but you can name it anything you like. The important part is the use of the asterisk, which is what enables the collection of an arbitrary number of positional arguments into a tuple. The other options do not provide this specific functionality. For instance, keyword arguments are designated with double asterisks (**) and are used to pass arguments by name rather than position. Default parameters provide default values for the function parameters, and varargs, while

For instance, if you define a function like this:

for arg in args:

print(arg)

You can call this function with multiple arguments, and it will print each one:

example_function(1, 2, 3, 'hello')

This will output:

1

2

3

hello
