Short Answer

Expert verified

Answer: In Python, you can use the input() function to prompt the user for input and assign it to a variable as follows: ```python weekly_sales = float(input("Please enter the amount of sales for the week: ")) ``` In Java, first import the Scanner class, create a Scanner object, and then prompt the user for input and assign it to a variable: ```java import java.util.Scanner; Scanner scanner = new Scanner(System.in); System.out.print("Please enter the amount of sales for the week: "); double weeklySales = scanner.nextDouble(); scanner.close(); ```

Step by step solution

Prompt the user for input and assign it to a variable

Use the input() function to display a message to the user, asking for the amount of sales for the week. Assign the resulting input to a variable, which will store the sales data. ```python weekly_sales = float(input("Please enter the amount of sales for the week: ")) ``` #For Java#

Import the Scanner class

Import the Scanner class from the java.util package, which will allow us to read the user's input. ```java import java.util.Scanner; ```

Create a Scanner object

Create a Scanner object called 'scanner' that will read the user's input. ```java Scanner scanner = new Scanner(System.in); ```

Prompt the user for input and assign it to a variable

Use the Scanner object to display a message to the user, asking for the amount of sales for the week. Assign the resulting input to a variable, which will store the sales data. Don't forget to close the scanner object after reading the input. ```java System.out.print("Please enter the amount of sales for the week: "); double weeklySales = scanner.nextDouble(); scanner.close(); ```
