isPrime Function
A prime number is an integer greater than 1 that is evenly divisible by only 1 and itself. For example, the number 5 is prime because it can only be evenly divided by 1 and 5. The number 6, however, is not prime because it can be divided by 1, 2, 3, and 6.
Write a Boolean function named isPrime, which takes an integer as an argument and returns true if the argument is a prime number, and false otherwise. Demonstrate the function in a complete program.
TIP: Recall that the % operator divides one number by another and returns the remainder of the division. In an expression such as num1 % num2, the % operator will return 0 if num1 is evenly divisible by num2.

5. A prime number is a number that is only evenly divisible by itself and 1. For example, the
number 5 is prime because it can only be evenly divided by 1 and 5. The number 6, how-
ever, is not prime because it can be divided evenly by 1, 2, 3, and 6.
Write a Boolean function named is_prime which takes an integer as an argument and
returns true if the argument is a prime number, or false otherwise. Use the function in a
program that prompts the user to enter a number then displays a message indicating
whether the number is prime.
6. In another program, use the function you wrote in question 5 to print the prime numbers
between 1 and 100 using for loop.

In mathematics, a harshad number is an integer that is evenly divisible by the sum of its digits. For example, 18 is a harshad number because 1 + 8 = 9 and 18 is divisible by 9. Write a function that returns the number of harshad numbers between 1 and 1000000.
: Given a boolean expression consisting of the symbols 0 (false), 1 (true), & (AND), I (OR), and / (XOR), and a desired boolean result value result, create a function that counts the number of ways the expression may be parenthesized such that it evaluates to result. The expression should be completely parenthesized (for example, (0) A(1)) but not excessively (for example, (((0)) / (1))).EXAMPLE \scountEval("l/01011", false) yields 2 counts."0&0&0&1All0", true) = 10

- A prime number is a number that is only evenly divisible by itself and 1. For example, the number 5 is prime because it can only be evenly divided by 1 and 5. The number 6, however, is not prime because it can be divided evenly by 1, 2, 3, and 6. Design a Boolean function called isPrime, that accepts an integer as an argument and returns True if the argument is a prime number, or False otherwise. Use the function in a program that prompts the user to enter a number and then displays a message indicating whether the number is prime. The following modules should be written: getNumber, that accepts a Ref to an integer, prompts the user to enter a number, and accepts that input isPrime, that accepts an integer as an argument and returns True if the argument is a prime number, or False otherwise showPrime, that accepts an integer as an argument , calls isPrime, and displays a message indicating whether the number is prime The main module, that will call getNumber and showPrimearrow_forwardCyclops numbersdef is_cyclops(n):A nonnegative integer is said to be a cyclops number if it consists of an odd number of digits so that the middle (more poetically, the “eye”) digit is a zero, and all other digits of that number are nonzero.

Enjoy your extra day! >>>leapYear(1901) The year 1901 is not a leap year. Description: Write a function which calculates whether or not a given year is a leap year and has 366 days instead of 365. A general algorithm is as follows: 1. A year will be a leap year if it is divisible by 4 but not by 100. 2. If a year is divisible by 4 and by 100, it is not a leap year unless it is also divisible by 400. Years such as 1996, 1992, 1988 and so on are leap years because they are divisible by 4 but not by 100. For century years, the 400 rule is important. Century years (ex: 1900, 1800, 1700) are exactly divisible by 4 AND exactly divisible by 100. They are not divisible by 400 and are thus not leap years. You fuction should print out "The year XXXX is a leap year. Enjoy your extra day!" if the year XXXX is a leap year. Print "The…arrow_forward

You have been provided with two function definitions: The is_prime () function takes an integer parameter number, and returns True if number is prime and False otherwise. The get_next_prime () function also takes a single integer parameter number, and returns the first prime number larger than it. You must not change the implementation of these 2 functions. Complete the get_primes_list() function that takes a single list of integers called numbers as parameter. You can assume that the integer items in this list will be non-negative. The function must update this list so that items that are not prime numbers are updated to the first prime number larger than them. To implement this function you must call both the is_prime () and get_next_prime () functions. Some examples of the function being called are shown below.
