Write a program that reads a one-line sentence as input and then displays
the following response: If the sentence ends with a question mark (?) and
the input contains an even number of characters, display the word Yes. If the
sentence ends with a question mark and the input contains an odd number
of characters, display the word No. If the sentence ends with an exclamation
point (!), display the word Wow. In all other cases, display the words You
always say followed by the input string enclosed in quotes. Your output
should all be on one line. Be sure to note that in the last case, your output
must include quotation marks around the echoed input string. In all other
cases, there are no quotes in the output. Your program does not have to
check the input to see that the user has entered a legitimate sentence.
Write a program that reads from the user a character ('q' or 'c').
If the character is 'c', the program reads from the user the radius rof a circle and prints its area.
• If the user enters 'q', the program asks the user to enter the length and width of a quadrilateral. We
assume the quadrilateral is either a square or rectangle. You should print if the quadrilateral is square
or rectangle.
• Otherwise, it prints "Wrong character"
PS: Use the following formulas:
area of circle=3.14*r
Sample Run1:
Enter a character (q or c): q
Enter the Length and Width: 80 150
|It is a rectangle
Sample Run2:
Enter a character (q or c): q
Enter the Length and Width: 80 80
It is a square
Sample Run3:
Enter a character (q or c): c
Enter the radius: 2
The area of the circle is 12.56
Sample Run4:
Enter a character (q or c): d
Wrong character
Write a program that generates a random number in the range from 1 through 100
After generating the random number, the user is to guess the number. If the user’s guess is higher than the random number, the program should display “Too high, try again”
If user’s guess is lower than the random number, the program should display “Too low, try again”.
If the user guesses the number, the program should congratulate the user and then generate a NEW random number so the game can start over.

For example, (2, 2) is inside the rectangle and (6, 4) is outside the rectangle, as shown in the Figure. (Hint: A point is in the rectangle if its horizontal distance to (0, 0) is less than or equal to 10 / 2 and its vertical distance to (0, 0) is less than or equal to 5 / 2.) Here are sample runs of the program: Sample 1: Enter a point with two coordinates: 2 2 Point (2.0, 2.0) is in the rectangle Sample 2: Enter a point with two coordinates: 6 4 Point (6.0, 4.0) is not in the rectangle Analysis: (Describe the problem including input and output in your own words.)

In other words run your code with sample outputs.arrow_forward1. Write a pyrhon program that prints out a classic hangman stick figure. The program should ask the user to enter a number from 1-6 and the corresponding hangman should be printed. The value the user inputs corresponds to the number of incorrect guesses in a real hangman game and so the completeness of the hangman will correspond to the number of ‘incorrect guesses’ inputted by the user (e.g., if the user enters 1, then only the head of the hangman will be printed; full example below). Example:Enter a number from 1-6: 1O Enter a number from 1-6: 2O|Enter a number from 1-6: 3O\||Enter a number from 1-6: 4O\|/|Enter a number from 1-6: 5O\|/|/Enter a number from 1-6: 6O\|/|/ \ 2. Modify your program from problem 1 so that the user input is checked to be a validsingle digit (1-6) before printing the corresponding hangman. If the input is not valid, theninstead of a hangman the following message should be printed “Invalid input: you must enter asingle number from 1-6.” Example:Enter a…arrow_forward

The right-angle point is at (0, 0), and the other two points are at (200, 0), and (0, 100).

Sample runs of the program are given below: Enter a point's x- and y-coordinates: 100.5 25.5 The point is in the triangle Enter a point's x- and y-coordinates: 100.5 50.5 The point is not in the trianglearrow_forward
- Write a program that asks the user to enter the three sides (a, b and c) of a triangle as double values. Assume that the user will enter three valid sides that can form a triangle, your program should perform the following tasks: If the three sides are equal, the program displays "Equilateral" on the screen. • If any two sides are equal, the program displays "Isosceles". If the sum of the squares of any two sides is equal to the square of the third one, for example (3? + 42 = 5) then the program displays "Right" • Otherwise, the program displays "Scalene" as well as the perimeter of the triangle which is the sum of all three sides. Sample Run 1: Enter three sides: 4.2 4 5 Sample Run 2: Enter three sides: 111 Equilateral Scalene Perimeter of triangle is: 13.2 Sample Run 3: Enter three sides: 3 4 5 Right Sample Run 4: Enter three sides: 8.2 5 8.2 Isosceles 64°Farrow_forwardWrite a program that prompts the user to enter apoint (x, y) and checks whether the point is within the rectangle centred at (1, 1)with width 10 and height 5.

- You have been asked to write a program to play rock-paper-scissors. Your program will ask the user to input a number 0, 1, or 2 to denote rock, paper, and scissors respectively. Your program will then randomly generate a number 0, 1, or 2 to denote the computer’s hand. The rules for the game are: •A scissor can cut paper. •A rock can knock a scissor. •A piece of paper can wrap a rock. Let the game run continuously until either the user or the computer wins 3 times, displaying the outcome of each hand. At the end of the game, display a message indicating whether the user or the computer wins Helpful Hint: import random player2= random.randint(0, 2)arrow_forwardWrite a program that plays the popular scissor-rock- paper game. (A scissor can cut a paper, a rock can knock a scissor, and a paper can wrap a rock.) The program randomly generates a number 0, 1, or 2 representing scissor, rock, and paper. The program prompts the user to enter a number 0, 1, or 2 and displays a message indicating whether the user or the computer wins, loses,or draws.arrow_forwardWrite a program for a “6/15 Lottery Game”. Please take note of the following: 1. It must prompt the user to input a digit for about six times between 0 to 15 only. The output display must specify that it’s “Digit 1”, “Digit 2”, and so on up to “Digit 6”.2. If the inputted digit is greater than 15, the program will notify the player about the incorrect input displaying: “Error! Please input a digit between 0 and 15 only! Repeat your Selection!” And the program will be terminated.3. If at least one digit matched (exact array position and digit) from the Lottery draw, then the output display must be, as an example: “1 Match! Your Bet is free for the next draw!”4. If no digit matched from the Lottery draw, then the output display must be, as an example: "Sorry. No Exact Match Found. Try Again! "5. Note that repetition of input digit chosen by the player is allowed. 6. And finally, if all digit matches, it will give an output display, as an example: "Congratulations! You are a…arrow_forward
