1995
the output is:
Yes
Ex: If the input is:
42,000
or
1995!

- 1 – Write a python program that prompts the user to enter a string and checks if the string contains vowels or not. If the string contains any vowels, it should print “This string contains vowels” otherwise it should print “This string does not contain any vowels”.arrow_forwardExercise I- Medicine Write a program that asks the user to enter the name of the medicine (t for ThroX, f for FeliX), his mass. The user should enter as well if he has a prescription or not. The program will calculate the dosage using: age and his ThroX without prescription -The max dosage should be 0.75 mL -The dosage = mass / 150 -The number of pills per day to take is 1 ThroX with prescription -The dosage =mass * 3 / 150 -The number of pills per day to take is 5 FeliX with prescription -The dosage = 0.77 mL FeliX without prescription -The dosage should be between 0.3 and 0.7 -The dosage = mass * 0.009 -The number of pills per day to take is 2 -The number of pills per day to take is 6 The program should display the dosage and the number of pills to be taken per day if the requirements are full filled, otherwise it display "Please check your doctor for a prescription". In case the medicine does not exist in the database, the program display “Your medicine is not in our database!"…arrow_forwardProblem: Feed Nibble Monster Till Full Write a program that generates a number in [0, 500] at the beginning -- this corresponds to how hungry the monster is -- and keeps asking the user to feed the monster until that number falls to zero. Each time the user feeds the monster a nibble, hunger decreases by the decimal value of the character (i.e. if the user feeds 'A' hunger decreases by 65). But when the user feeds the monster some character that isn't a nibble, the hunger increases by the decimal value of the character (since puking depletes energy). Use while loop. Sample runs: Notice the loop exits after one iteration, because hunger was very low and one nibble made the monster full: Notice hunger increasing after non-nibble (pink highlight): Notice that the program just keeps going when the user feeds the monster only non-nibbles. Do you think the program will keep running forever if the user never gives the monster nibbles?arrow_forward
- Extend to cast the double to an integer, and output that integer. Enter integer: 99 Enter double: 3.77 Enter character: z Enter string: Howdy 99 3.77 z Howdy Howdy z 3.77 99 3.77 cast to an integer is 3arrow_forward(1) Prompt the user for a string that contains two strings separated by a comma. Examples of strings that can be accepted: Jill, Allen Jill , Allen Jill,Allen Ex: Enter input string: Jill, Allen (2) Report an error if the input string does not contain a comma. Continue to prompt until a valid string is entered. Note: If the input contains a comma, then assume that the input also contains two strings. Ex: Enter input string: Jill Allen Error: No comma in string. Enter input string: Jill, Allen (3) Extract the two words from the input string and remove any spaces. Store the strings in two separate variables and output the strings. Ex: Enter input string: Jill, Allen First word: Jill Second word: Allen (4) Using a loop, extend the program to handle multiple lines of input. Continue until the user enters q to quit. Ex: Enter input string: Jill, Allen First word: Jill Second word: Allen Enter input string: Golden , Monkey First word: Golden Second word: Monkey Enter input string:…arrow_forwardIN PYTHON Write a script which uses the input function to read a string, an int, and a float, as input from keyboard prompts the user to enter his/her name as string, his/her age as integer value, and his/her income as a decimal. For example your output will display as: Mark is 30 years old and his income is 2000 Please show code.arrow_forward
- Your program will prompt the user for the following information: current population number of yearly births from the previous year number of yearly deaths from the previous year number of years into the future for your predictive value of the future population. You will then compute the following: birth rate death rate growth rate the predicted future population Assignment Notes: To allow the user to input the numeric data (such as current population) it is necessary to use the input function. The input function takes a string in parenthesis that prompts the user what to enter. The computer then waits until the user types a response, terminated by the user typing the Enter key. A string, as a sequence of characters, is returned to the variable on the lefthand side of the assignment statement. For example: currPopulation = input(“Enter the current US population”) The data in currPopulation is a string (because that is what the input statement does) but we need it to be a number…arrow_forwarduser if the guess is too high or too low or is correct. 3.

- السبت ۲ أكتوبر المحاولة رقم 1 :2 HW • Write a program that computes the average of 5 students grades which are entered by the user. Write a program that converts pounds into kilograms. The program prompts the user to enter a number in pounds, converts it to kilograms, and displays the result. One pound is 0.454 kilograms. محتوى إضافي؟ يمكنك إضافة نص وملفات تدعم إجاباتك. إضافة محتوی إرسال الحفظ لوقت لاحقarrow_forwardExercise 4: Selection and loop statements A certain professor gives 5-point quizzes that are graded on the scale 5-A, 4-B, 3-C, 2-D, 1- F, 0-F. Write a program that accepts a quiz score as an input and prints out the corresponding grade. The input data must be a float numbers and between 0 and 5 Example Input : Quiz score: 3 Output: The grade is C. Exercise 4 Write an improved version of the future value program from Chapter 2. Your program will prompt the user for the amount of the investment, the annualized interest rate, and the number of years of the investment. The program will then output a nicely formatted table that tracks the value of the investment year by year. Your output might look something like this:arrow_forwardMUST BE IN PYTHON PROGRAMMING CODE!!!!! NO C++ or Java!! Directions: Design a program with a loop that lets the user enter a series of names (in no particular order). After the final person’s name has been entered, the program should display the name that is first alphabetically and the name that is last alphabetically. For example, if the user enters the names Kristin, Joel, Adam, Beth, Zeb, and Chris, the program would display Adam and Zeb. Additional requirements: Note that the possible set of input values can include negative, 0, or positive values, but not the sentinel value of -99. DESIGN HINT: • When determining the largest (or smallest) value in a set of numbers, remember to use variables to keep track of the current largest (or smallest) number found thus far. These variables can then be used as a comparison to each subsequent input number to see if the new number is larger (or smaller) than the current largest (or smallest) number and updated appropriately.
