Leap Year: The earth doesn't take exactly 365 days to revolve around the sun and because of this we have leap years
roughly every 4 years to make up the difference. The exact rule is:
• Years divisible by 4 are leap years
• except if they are also divisible by 100 and then they are not leap years (so 1900 was not a leap year),
• unless they are also divisible by 400 and then they ARE leap years (so 2000 was a leap year).
Part 1) Write a function in Python that takes as input a number, the year, and determines if it is a leap year or not. The
function should return True if it is a leap year and False otherwise.
Part 2) Write a main function to test out your leap year function on a few different illustrative inputs.
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.

Question :
The Card Game
One day, Fred and his N friends were playing a card game in which each player throws a
card with a number written on it. The cards are such that a number X is written on front of
the card, and the negative of that number is written on the back side of the card. This game
has the following rules: -
Each of the N players is asked to throw a card. After all the N cards are thrown, Fred has to
flip one or more cards in consecutive order, only once.
Your task is to help Fred flip the cards in such a way that the sum of the numbers, on front
face of the cards, is the maximum.

- 4) Roll the dice 2 Make a program that tests the probability of a certain score when rolling x dice. The user should be able to choose to roll eg 4 dice and test the probability of a selected score eg 11. The program should then do a number of simulations and answer how big the probability is for the selected score with as many dice selected. There must be error checks so that you cannot enter incorrect sums, for example, it is not possible to get the sum 3 if you roll 4 dice. TarningsKast2 How many dices do you want to throw? 11 Which number do you want the probability for? The probability the get the number 11 with 4 dices is 7.19% Calculatearrow_forwardQ5: Write in Python program: After calculating the ranking score according to the ALES (Academic Postgraduate Exam) score, foreign language score and graduation grade point average of the candidate applying for graduate education, write the program in python, which will be able to enter the ranking on the screen. (All points are given over a hundred.) Ranking Score = 50% of ALES + 25% of foreign language score + 25% of graduation grade point average It is calculated by the formula. If the ranking score is 60 and above, it can enter the ranking, otherwise it cannot.

Consider the following Python code, where the variables level and threshold have integer values: alarm = 3 if level = threshold: if level < 100: alarm = 1 alarm = 2 What initial values for variables level and threshold guarantee that variable alarm ends up with the value of 2 after the code has executed? When level is 200 and threshold is 99 When level is 4 and threshold is 5 ☐ When level is 200 and threshold is 100 When level is 400 and threshold is 300 When level is 5 and threshold is 4 When level is 3 and threshold is 4 When level is 1 and threshold is 2 O When level is 10 and threshold is 10arrow_forward

Their "magnificence" is quantified by the rather simple process of counting the exact number of tail feathers and multiplying this by the difference in the length of the minimum and maximum lengths of tail feather. You are to write a simple program that will allow the user to enter the length of each tail feather individually and keep on entering feathers until a -1 is entered. The program will then return the quantified "magnificence" factor.arrow_forwardDiscrete Mathematics: Assignment details: Replace all the 0 (Zero) digits in your ID by 4.

- 15. Speed Conversion ChartYour friend Amanda, who lives in the United States, just bought an antique European sports car. The car’s speedometer works in kilometers per hour. The formulafor converting kilometers per hour to miles per hour is:MPH = KPH * 0.6214In the formula, MPH is the speed in miles per hour and KPH is the speed in kilometersper hour. Amanda is afraid she will get a speeding ticket, and has asked you to write aprogram that displays a list of speeds in kilometers per hour with their values convertedto miles per hour. The list should display the speeds from 60 kilometers per hourthrough 130 kilometers per hour, in increments of 5 kilometers per hour.

The players each take turns rolling two die. b. A player scores the sum of the two dice thrown (unless the roll contains a 1): If a single number 1 is thrown on either die, the score for that whole turn is lost (referred to as “Pigged Out”). A 1 on both dice is scored as 25. c. During a single turn, a player may roll the dice as many times as they desire. The score for a single turn is the sum of the individual scores for each dice roll. d. The first player to reach the goal score wins unless a player scores higher subsequently in the same round. Therefore, everyone in the game must have the same number of turns. Execution and User Input This program is quite interactive with the user(s) and will take in the following information; please review the sample input / output sessions for details; we describe them again here emphasizing input.

- 4. Area of a Rectangle • Write a program that compares the area of two rectangles. You can do this several ways. one way is to add the length and width of each rectangle to get it's area and then compare the two areas together. • The program should ask for the length and width of two rectangles and then tell the user which rectangle has the greater area, or if the areas are the same. • The area of a rectangle is the rectangle's length times its width. Name the source code file yourName HW4.py. • Test and run the program. Capture the output console and save it as an image file named yourName HW4 output.jpg. • Submit the py and the image files through Canvas.

Now, the minute hand doesn't rotate by the angle 2π/3600 each second, but now it moves according to different angle x. You can assume that coordinates of the centre of the clock are (0, 0) and the length of the minute hand is l. One endpoint of the minute hand is always located at the clock centre; the other endpoint is initially located at the point (0, l). One second later, Harry observes that this endpoint is at distance d above the x-axis, i.e., the y-coordinate of this endpoint is equal to d. Harry is curious about where the minute hand will be (specifically, its y-coordinate) after t seconds. Because t can be very large, Harry can't wait for that moment.
