A word is called as a good word if all the letters of the word are distinct. That is, all the letters of the word are different from each other letter. Else, the word is called as a bad word. This can be continued based on the user input is 'Y'.
At a certain university, students have to submit their exams online. The administration decides that for each minute of late submission, 5 points are deducted. Write a program that asks the user for his initial grade and the late submission time (in minutes), and then displays the final result.
Sample Run 1:
Enter your initial grade: 82
Enter the late submission time (in minutes): 6
Your final grade is 52
Sample Run 2:
Enter your initial grade: 115
Grades should be between 0 and 100
Sample Run 3:
Enter your initial grade: 43
Enter the late submission time (in minutes): 10
Your final grade is 0
Sample Run 4:
Enter your initial grade: 72
Enter the late submission time (in minutes): -2
Time should be positive
Write a program (or modify the one written for Lab 2) that displays the following menu and prompts the user for a selection. Once the selection has been made, display the selection back to the user. Then, ask the user for two numbers and perform the selected operation (+, -, *, /). Display the results back to the user (e.g. 2 + 3 = 5). When dividing, display an error message if the second number (denominator) is 0.
1) Add two numbers 2) Subtract two numbers 3) Multiply two numbers 4) Divide two numbers
9) Exit program
The program should:
contain header comments as shown in class
display a "hello" message before presenting the menu
display the menu
prompt the user for selection
display the selection back to the user
if the selection was invalid, display error message to user and then go to goodbye message
if the selection was valid, prompt the user for two numbers
if the operation is division, and the second number is 0, display error message to user and then go to goodbye message…

The program should ask the user to provide an input for the carbon concentration at the surface (cs), and the concentration of carbon in the bulk (c0).arrow_forwardWrite a program that will figure out the required change for a purchase. Start by asking the user for the price of the product and the amount paid. (We are expecting that the user will give a larger value for the amount paid.) Read in each of these values as a double. Report back to the user the number of each denomination of change due. You are not just telling the user the amount of money he gets back. Hint: Working with integers is much easier. The modulo operator is your friend for this assignment. Also, note that pennies can be tricky due to the poor real number to binary conversions. (Remember that 1.00 could actually be stored as 0.9999999999997.) Do not include five-dollar bills, ten-dollar bills, etc. Only show coins and one-dollar bill amounts.

- Get three exam grades from the user and compute the average of the grades. Output the average of the three exams. Together with the average, also include a Remark: Passed in the output if the average is greater than or equal to 70, otherwise output Remark: Failed. NOTE: Your source code must display any of the given sample output below. It means your source code should be flexible enough to meet any of the given sample output. Your source code output must be identical to any of the given sample output. It means you have to strictly follow what are the displayed text, labels, casing of characters in the sample output. OUTPUT 1: Enter Grade 1: 70 Enter Grade 2: 80 Enter Grade 3: 90 Average Grade: 80 Remark: Passed OUTPUT 2: Enter Grade 1: 50 Enter Grade 2: 60 Enter Grade 3: 70 Average Grade: 60 Remark: Failedarrow_forwardSometimes we write similar letters to different people. For example, you might write to your parents to tell them about your classes and your friends and to ask for money; you might write to a friend about your love life, your classes, and your hobbies; and you might write to your brother about your hobbies and your friends and to ask for money. Write a program that prints similar letters such as these to three people of your choice. Each letter should have at least one paragraph in common with each of the other letters. Your main program should have three method calls, one for each of the people to whom you are writing. Try to isolate repeated tasks into methods.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 program should then output each candidate’s name (Candidate), the number of votes received (Votes Received), and the percentage of the total votes received by the candidate (% of Total Votes). Your program should also output the winner of the election. Your program must contain at least the following functions: a function to determine the sum of votes. a function to output the winner of the election.arrow_forwardf. A laborant in a laboratory does a number of antigen tests in one day. Write a program that simulates the number of antigen tests done in a day in a laboratory, displays the number of positives and negatives, and calculates the % of positives in one day. Your program needs to first generate a random number that will show the number of tests done in a day. One laboratory in a day cannot do more than 100 tests and less than 1 (they do at least one). Then for each of the tests, your program needs to generate a random number to show whether they are positive or negative. In order to write this program, you need to have the following three functions used by the main function: test result (void): This function generates a test result. It should randomly return either one or zero. 1 means positive test result and 0 means negative test result. float positive percentage (int,int) : This function takes the total number of positives and the total number of tests and returns the % of positives.…arrow_forwardWrite a program to simulate the rolling of two dice. If the total of the two dice is 7 or 11.you win: you lose.

- Python For this lab, you will use a tuple to represent a student record. A student record consists of the student’s name, year, and GPA. For example, (“John”, “Senior”, 3.7) is a record for John who is a senior with a 3.7 GPA. You will write a program that prompts the user for the number of records to enter. Then it reads input from the user for each record. Remember that each record consists of a student’s name, year, and GPA. It then prints the record of each student as shown below. Functions: You will write the following functions: read_records(n) Read n number of records and return a list of records. print_records(records) Takes in a list of records and print each one. main() Prompts the user for the number of records to read, get a list of records from the user, and print the records. Optional: print the average GPA of the students.

Write a program that prompts for and takes any number of non-negative integers as input, and outputs the average and max. A negative integer ends the input and is not included in the statistics.

(Hint: A point is in the rectangleif its horizontal distance to (0, 0) is less than or equal to 10 / 2 and its verticaldistance to (0, 0) is less than or equal to 5.0 / 2.
