Question

in Python: you are to use the IsPrime() and NthPrime() functions implemented in the last assignment ot implement a program that repeatedly offers the user the following three menu options: F: Find the nth prime number T: Test a value to see if it is prime Q: Terminate the program The user selects an option by entering the associated letter, in uppercase or lowercase. Any other input should lead to a prompting of the user for a correct input. Depending on the option selected by the user program should perform the action described in the following. In response to a menu option input of F the program prompts the user to enter a positive (greater than 0) value. If a valid value is input, then the program, treating that value as its ordinal number equivalent, should output the prime number corresponding to that value. For example, an input value of one should result in the output of 2, the first prime number; an input of 2 results in the output of 3; and so on. If the user inputs an invalid number value (i.e., zero or a negative number) the program should output an appropriate error message, but take no additional action for the F option For a menu option input value of T the program prompts the user to enter a non-negative value (i.e., a value that is greater than or equal to zero), after which the program outputs a message indicating whether or not the input value is prime. The program responds to an invalid value with an appropriate message, and no additional action for the T option. An input of Q causes the program to terminate. Do not use constant-valued expressions as a loop control condition. When using the bool data type, the values True and False should be used, instead of 1 and 0.

Answer 1

The student will create a Python program with a menu that uses IsPrime() and NthPrime() to find the nth prime number, test if a number is prime, or terminate the program, while handling various user inputs and errors.

Step-by-step explanation:

The student is tasked with creating a program in Python that uses the IsPrime() and NthPrime() functions from a previous assignment to implement a menu-driven application. This program provides three options to the user:

• F: Find the nth prime number
• T: Test if a value is prime
• Q: Terminate the program

The program should handle both uppercase and lowercase input letters and prompt for correct input if an incorrect option is chosen. When the 'F' option is selected, the user should input a positive value to find the corresponding prime number. For 'T', the program should accept a non-negative value and confirm if it is prime. An input of 'Q' will exit the program. Error messages should be displayed for invalid inputs and no further action should be taken for that option.
