A Krishnamurthy number is a number which sum of the factorial of its digits is equal to the number itself. For example: Let us consider the number 145. Factorial sum = 1! + 4! + 5! = 1 + 24 + 120 = 145. Therefore 145 is a Krishnamurthy number. Other examples include: 1, 2, 40585. Write a program that does the following: • asks the user to input an integer. • computes whether the number is a Krishnamurthy number. • then finally prints the result. Note: You are not allowed to use the built-in function math.factorial.

Your program ends with the input 0. Display the maximum, minimum, and average as a floating-point number. Here is a sample run:Enter an integer, the input ends if it is 0: 1 2 -1 3 0The number of positives is 3The number of negatives is 1The maximum is 3.0The minimum is -1.0The average is 1.25arrow_forward
- (Converting a given date to the day number in the year) Write a program that prints the day number of the year, given the date is in the form month day year. For example, if the input is 1 1 05, the day number is 1; if the input is 12 25 05, the day number is 359. The program should check for a leap year. A year is a leap year if it is divisible by 4 but not divisible by 100. For example, 1992 and 2008 are divisible by 4, but not by 100. A year that is divisible by 100 is a leap year if it is also divisible by 400. For example, 1600 and 2000 are divisible by 400. However, 1800 is not a leap year because 1800 is not divisible by 400. Directions: Call 3 functions from your main. One to input data (pass parameters in a list) One to determine the result (use a value returning function to determine and return the result) One to display both the date and the result You can use two Python dictionaries to represent the number of days in each month for a regular and a leap year.

Your program should prompt the user to enter the amount of water in kilograms and the initial and final temperatures of the water.

- (Python) Please write a program that creates steps. You are expected to take in a single positive integer which will be used as the number of steps in your staircase. The program only accepts integers greater than 0 and less than 500. If 0 is entered a message stating "Your staircase has no steps." and if the user enters a value greater than or equal to 500, a message stating "I can't build a staircase that tall." For all other values not within the valid range or not integers an "Invalid staircase size provided." will be displayed to the user. The program will always run only once for each user input. One thing to note, the messages should be the return string from your printSteps() function and printed from the calling function. Additional Requirements: The very first step in the staircase will be left-aligned and for each subsequent level, the step will move above and to the right of the prior step. There are no spaces after the right of any of the steps.

The formula for computing the area of a regular polygon is n x s? Area 4 X tan Here, s is the length of a side. Write a program that prompts the user to enter the number of sides and their length of a regular polygon and displays its area.

For example, if an integer is 932, the sum of all its digits is 14.arrow_forward[Calculate grades’ average for a student] write a program that calculates the student grades’ average for a semester for the number of courses taken in that semester. Your program should do the following: 1.Read from user the number of courses (n) 2. Then, read the courses’ grades for n times (Hint: use a loop) 3.If a grade is grater than 100 or less than 0, ask the user to enter the grade again. 4.Calculate the average of grades using the following formula: average = (sum of grades) / n 5.Print out the average grade on the screen.
