1) Simple Calculator: In Python, implement a simple calculator that does the following operations: summation, subtraction, multiplication, division, sqrt, power, natural log and abs. a) Follow the instructions below: To work with the calculator, the user is asked to enter the first number, then the operation, and finally, a second number if required. Your code has to recognize the need for the second number and ask for it if required. After performing one operation, the calculator prints the output of the operation. After performing one operation, the calculator must not exit. It has to start again for the next operation. The calculator will be closed if the user writes 'e' as any input. Use functions to perform the operations and the appropriate conditions to prevent common errors such as entering characters as one of the numbers etc. b) Run your code and provide the results for at least one example per operation.

Looping for Statements Write a program that will display a multiplication table with the format shown below. The range of the table 2 10 10 20 30 100 X123 1123 X 3 10 2246 3369 2 4 10 20 30

PART A Write a Python program that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows. 1. When the program begins, a random number in the range of 1 through 3 is generated. If the number is 1, then the computer has chosen rock. If the number is 2, then the computer has chosen paper. If the number is 3, then the computer has chosen scissors. (Don’t display the computer’s choice yet.) 2. The user enters his or her choice of “rock”, “paper”, or “scissors” at the keyboard. (You can use a menu if you prefer.) 3. The computer’s choice is displayed. 4. A winner is selected according to the following rules: a. The rock smashes the scissors. b. Scissors cuts paper. c. Paper wraps rock. d. If both players make the same choice it is a tie. Print who the winner is. Part B: Once you have completed Part A continue playing, keeping track of how many wins, losses and ties. Add an item to the menu that asks if the user wants to Quit. Keep…

9: perfect.cpp) A number is called perfect if the sum of its divisors is equal to the original number. A number is called deficient if the sum of its divisors is less than the original number. A number is called abundant if the sum of its divisors is more than the original number. Write a program that answers the following questions: What numbers below 5000 are perfect? What odd numbers below 5000 are abundant? What are the relative proportions of deficient, abundant, and perfect numbers? 5000 should be in a global constant.

Java example to check if number is palidrom or not  Number will be entered by the user

In Coral Language 3.22 LAB: Loops: Countdown until matching digits   Write a program that takes in an integer in the range 20-98 as input. The output is a countdown starting from the integer, and stopping when both output digits are identical. Ex: If the input is: 93 the output is: 93 92 91 90 89 88 Ex: If the input is: 77 the output is: 77 Ex: If the input is: 9 or any number not between 20 and 98 (inclusive), the output is: Input must be 20-98 For coding simplicity, follow each output number by a space, even the last one. Use a while loop. Compare the digits; do not write a large if-else for all possible same-digit numbers (11, 22, 33, …, 88), as that approach would be cumbersome for large ranges.

Program Unit Score Calculator Console App Write a Python Console Application program that allows the user to enter the marks for different assessments in a unit, and computes the total mark and grade for the unit.  Here is the program logic specification: There are six assessment activities Quiz1, Quiz2, Quiz3, Quiz4, Lab Journal, Major Assignment and Final Exam. The four quizzes are worth 5 marks each, the Lab Journal is worth 10 marks, the Major Assignment is worth 30 marks and the Final Exam is worth 40 marks. The algorithm for computing the total mark for the unit is:  Total Mark = Quiz1+Quiz2+Quiz3+Quiz4+Major Assignment+ Lab Journal + Final Exam The following screenshot shows a successful test run:

Debugging Coin Toss The following program is meant to be a simple coin toss guessing game. The player gets two guesses (it’s an easy game). However, the program has several bugs in it. Run through the program a few times to find the bugs that keep the program from working correctly.   import random guess = '' while guess not in ('heads', 'tails'): print('Guess the coin toss! Enter heads or tails:') guess = input() toss = random.randint(0, 1) # 0 is tails, 1 is heads if toss == guess: print('You got it!') else: print('Nope! Guess again!') guesss = input() if toss == guess: print('You got it!') else: print('Nope. You are really bad at this game.')

6. A palindrome is a number or text phrase that reads the same backwards or forwards. For example, each of the following five-digit integers is a palindrome: 12321, 55555, 45554 and 11611. Write a program that reads a 5 digit integer and determines whether it is a palindrome. Hint: One way to do this is to use division (/) and modulus (%) operators to separate the number into individual digits.
