Question
Write a program in Python, in which the user can enter any number of positive and negative integer values, and then we display the total number of positive values entered and the total number of negative values entered. We are going to use a sentinel value (also known as a flag value) to control the loop. If the user wants to quit counting up positive and negative numbers, the user will enter a (q). The first line should print out a title that says something like “Practice 4: Counting the number of positive and negative values entered by the user”.

Transcribed Image Text:Counting the number of positive and negative values entered by the user!
Please enter first number (enter q to quit): 5
Please enter next number (enter q to quit): 4
Please enter next number (enter q to quit): -2
Please enter next number (enter q to quit): 0
Please enter next number (enter q to quit): -1
Please enter next number (enter q to quit): 100

- "Simon Says" is a memory game where "Simon" outputs a sequence of 10 characters (R, G, B, Y) and the user must repeat the sequence. Create a for loop that compares each character of the two strings. For each matching character, add one point to user_score. Upon a mismatch, end the loop. Sample output with inputs: 'RRGBRYYBGY' 'RRGBBRYBGY' User score: 4 Learn how our autograder works 487180.3542414.qx3zqy7 1 user_score= 0 2 simon_pattern = input() 3 user_pattern input() 4 5 for i in range(len(simon_pattern)): 6 if simon_pattern[i] user_score=4 7 8 9 10 == user_pattern[i]:arrow_forwardPositive integers start, stop, and step have been initialized. Write code using a loop to print out all integers from start to stop in steps of step, but not including stop itself. Numbers should be separated by a space, and there should be a newline at the end of the line. It's okay if there's an extra space at the end of the line as well. For example: Test int start=0, stop=51, step=5; Result 0 5 10 15 20 25 30 35 40 45 50arrow_forwardAssignment4C: Heads or Tails? It is said that a perfectly fair coin will return heads 50% of the time, and tails 50% of the time. Rather than have you test this theory by flipping a coin yourself, let's use a random number generator and loops to determine the truth. Create a program that prompts the user for a number of coin flips. Then, “flip a coin" that many times by using a random number generator that produces either a 0 or 1. Afterwards, show the user how many times it landed on heads (0) and tails (1) and calculate the frequency for each. Inform the user if heads or tails was the more frequency result, or if they were equal. Call the file name Assignment4C (.java, .cs, .cpp) and the class name Assignment4C. Example outputs are shown below. Note that due to using a random number generator, you may not get the same numerical results – but the formatting and wording should be the same. User input is indicated in bold. Sample Output #1: How many times do you want to flip the coin?:…arrow_forward
- In mathematics, the notation n! represents the factorial of the nonnegative integer n. The factorial of n is the product of all the nonnegative integers from 1 to n. For example, 7! = 1 X 2 X 3 X 4 X 5 X 6 X 7 = 5,040 and 4! = 1 X 2 X 3 X 4 = 24 Write a program that lets the user enter a nonnegative integer then uses a loop to calculate the factorial of that number. Display the factorial. in pythonarrow_forwardPrimeAA.java Write a program that will tell a user if their number is prime or not. Your code will need to run in a loop (possibly many loops) so that the user can continue to check numbers. A prime is a number that is only divisible by itself and the number 1. This means your code should loop through each value between 1 and the number entered to see if it’s a divisor. If you only check for a small handful of numbers (such as 2, 3, and 5), you will lose most of the credit for this project. Include a try/catch to catch input mismatches and include a custom exception to catch negative values. If the user enters 0, the program should end. Not only will you tell the user if their number is prime or not, you must also print the divisors to the screen (if they exist) on the same line as shown below AND give a count of how many divisors there are. See examples below. Your program should run the test case exactly as it appears below, and should work on any other case in general.

If the user enter height as 4 Then the triangle output is 1 1 2 1 2 3 1 2 3 4 We make the following assumptions • There is no space between the margin and first number in each row • There could be a space after the last number on every line • There is pne space between numbers on every line • There maybe a newline at the end of last line There is one test-case to check your code, there are two hidden testcases that tests correctness of your code 376584 2469arrow_forward
- Write a program Digits that prompts the user to input a positive integer and then outputs the number reversed and the sum of the digits. For example, if the user enters the number 3456, then your program should output 6543 and the sum as 18. Use a while loop. EXAMPLE OUTPUT: Enter an integer: 3478246 Number reversed: 6428743 Sum of digits: 34 You may assume the user enters a number smaller than the max int (2,147,483,647).arrow_forwardThe following loop will end when.. a =" while a!='xyz': a = input() a. the user inputs the string 'xyz' (without the apostrophes) b. the user inputs anything other than the string 'xyz' (with the apostrophes) c. the user inputs the string 'xyz' (with the apostrophes) d. the user inputs anything other than the string 'xyz' (without the apostrophes)arrow_forwardWrite a complete program to generate a username based on a user's first and last name. Part One: Get a Valid First and Last Name ask the user for and read in their first and last name use a loop to validate the first name: it must be at least one character long and it must start with a letter use a loop to validate the last name: it must not contain any spaces Hint: use a nested loop. The outer loop will iterate until there is valid input. The inner loop will check each character in the String to see if any of them are whitespace. Part Two: Generate a Username generate a two-digit random number (i.e., a random number between 10 and 99, inclusive) create a username that is the following data concatenated: the first letter of their first name in lower case the first five characters of their last name in lower case; if the name is shorter than five characters, use the whole last name the two-digit number output the username to the user Additional Coding Requirements code…arrow_forward
