Mastering Python Functions

What is the correct syntax to define a function in Python?

• create function_name(parameters)

• function function_name(parameters)

• function_name(parameters) = {}

• def function_name(parameters):

How do you pass a default argument to a function in Python?

• You define a function with parameters only: def function_name(param1):

• You cannot use default arguments in Python functions.

• You define a function with default arguments like this: def function_name(param1=default_value):

• You must declare default arguments after all required parameters.

What keyword is used to return a value from a function?

• yield

• send

• output

• return

Can a function in Python return multiple values? If so, how?

• A function can only return one value in Python.

• Yes, a function in Python can return multiple values by using commas.

• Functions in Python cannot return any values.

• Multiple values can only be returned as a list.

What is the purpose of the *args and **kwargs in function definitions?

• *args allows for a fixed number of arguments; **kwargs is for static arguments.

• *args is used to define default values; **kwargs is for type hints.

• *args is for variable positional arguments; **kwargs is for variable keyword arguments.

• *args is for keyword arguments; **kwargs is for positional arguments.

How do you call a function with keyword arguments in Python?

• You call a function with keyword arguments by using the syntax func(arg_name=value).

• You invoke a function with keyword arguments using func(arg=value).

• You can call a function with keyword arguments by writing func(arg_name:value).

• You call a function by using func(value=arg_name).

What happens if you do not provide a return statement in a function?

• The function returns None.

• The function returns an empty string.

• The function throws an error.

• The function executes but does not return anything.

How can you define a function that accepts an arbitrary number of positional arguments?

• def my_function(arg1, arg2): pass

• def my_function(args): pass

• def my_function(**kwargs): pass

• def my_function(*args): pass

What is the difference between positional and keyword arguments in function calls?

• Positional arguments are ordered, while keyword arguments are named.

• Keyword arguments must always come before positional arguments in a function call.

• Positional arguments can only be used in classes, while keyword arguments are for functions.

• Positional arguments are named, while keyword arguments are ordered.

How do you define a function that takes a variable number of keyword arguments?

• def my_function(**kwargs): pass

• def my_function(args): pass

• def my_function(*args): pass

• def my_function(arg1, arg2): pass
