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…
