Chapter 5: Problem 17

The following statements call a function named show_data. Which of the statements passes arguments by position, and which passes keyword arguments? a. show_data(name='Kathryn', age=25) b. show_data('Kathryn', 25)

Short Answer

Expert verified

Based on the provided information, determine which of the given statements call a function using arguments passed by position and which call a function using keyword arguments. a) show_data(name='Kathryn', age=25) b) show_data('Kathryn', 25) Answer: Statement (a) calls a function using keyword arguments, while statement (b) calls a function using arguments passed by position.

Step by step solution

Understand Passing arguments by position

When a function is called, the arguments are passed by position, which means that the values of the arguments are assigned according to their order in the function definition. The order in which the arguments are passed in the function call should match the order of the parameters in the function definition.

Understand Passing keyword arguments

Keyword arguments are another way to pass values to a function. In this method, each argument is assigned to a specific parameter using the parameter name followed by an equal sign (=) and the value to be assigned. This way, the order of the arguments does not matter, as long as the correct parameter names are used.

Analyze the given statements and determine the argument-passing method used

Now let's analyze each statement and determine which method is used for passing the arguments. a. show_data(name='Kathryn', age=25) In this statement, the arguments are assigned to the parameters using their names, i.e., name='Kathryn' and age=25. Therefore, this statement is an example of passing keyword arguments. b. show_data('Kathryn', 25) In this statement, the arguments are passed in order as ('Kathryn', 25). The order of these arguments should match the order of the parameters in the function definition. Therefore, this statement is an example of passing arguments by position.

Conclusion

In conclusion, statement (a) passes keyword arguments, and statement (b) passes arguments by position.
