What is the meaning of the keyword parameter in a function?

The keyword parameter in a function refers to the method of passing arguments to a function by specifying the parameter name along with its corresponding value. This approach allows for greater clarity and flexibility in function calls.

When you define a function with parameters, you can call that function using the keyword arguments format. For example, if a function is defined as def my_function(param1, param2):, you can call it using my_function(param2='value2', param1='value1'). In this case, you are explicitly stating which value corresponds to which parameter by using their names, which makes the code easier to read and understand. This is particularly useful when a function has several parameters, or when some of them have default values.

The other options do not capture the complete picture of what keyword parameters represent. For instance, the determination by the argument's value lacks the aspect of naming, while stating that it is fixed suggests a lack of flexibility which is incorrect. Lastly, the idea that it is always the first argument contradicts the fundamental feature of keyword arguments where the order does not matter as long as the names are specified.
