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…

- Party-On sells individual hot/cold cups and dessert plates for parties. SueChen wants a program that allows her to enter the price of a cup, the price of a plate, the number of cups purchased, and the number of plates purchased. The program should then calculate the total cost of the purchase, including the sales tax. Finally, the program should display the total cost on the screen. Desk-check your solution’s algorithm using $0.50 as the cup price, $1 as the plate price, 35 as the number of cups, 35 as the number of plates, and 2% as the tax rate. Then desk-check it using $0.25, $0.75, 20, 10, and 6%.arrow_forward3. Random Symbol Guessing Game Write a program that generates a random symbol and asks the user to guess what the symbol is. If the user's guess has a higher ASCII number than the random symbol, the program should display "Symbol ASCII too high, try again." If the user's guess has a lower ASCII number than the random symbol, the program should display "Symbol's ASCII too low, try again." The program should use a loop that repeats until the user correctly guesses the random symbol.arrow_forwardPart 4 Add this comment: # Ass 1: Part 4 Write a program that generates a random number in the range of 1 through 100, and asks the user to guess what the number is. If the user's guess is higher than the random number, the program should display "Too high, try again." If the 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 by displaying "You won, congratulations.". Samplel: Please enter your guess value: 10 Too low, try again. Please enter your guess value: 15 Too low, try again. Please enter your guess value: 30 Too low, try again. Please enter your guess value: 50 Too low, try again.

The user enters the values of coefficients a, b, c and d. The program should test each integer starting from -50 to 50, and each time the equation is equal to zero, it prints its value as well as "is a solution". At the end, it displays the total number of positive integers found. Note that if the equation has more than one solution, the plural word “solutions" is used in the output.
