What is the purpose of keyword arguments in function definitions?

• A. To allow functions to accept unlimited arguments
• B. To make it mandatory for the caller to specify the argument order
• C. To enhance code readability and allow arguments to be specified by name
• D. To limit the types of values that can be passed to the function

Answer: (C)

Keyword arguments serve the purpose of enhancing code readability and allowing arguments to be specified by name in function definitions. This feature provides several advantages. When using keyword arguments, the order in which you pass the arguments does not matter, as they are associated with their respective parameter names. This can make the code more understandable because it is clear what value is being assigned to what parameter, especially when a function takes multiple arguments or when default values are provided. For example, when defining a function with keyword arguments, a caller can specify arguments in any order: ```python def example_function(a, b, c=10): print(a, b, c) # Calling with keyword arguments example_function(b=2, a=1) ``` In this case, it's clear that `1` is given to `a` and `2` is given to `b`, regardless of the position in the argument list. This practice not only improves clarity but also helps prevent errors that may arise from matching the wrong values to parameters. The other choices do not reflect the true purpose of keyword arguments. While there are scenarios where functions can accept unlimited arguments, that feature pertains to *variadic arguments*, not keyword arguments. Similarly, keyword arguments help reduce the need
