How can I write a python  program using the  void functions and value-returning functions. It requires a main function and two custom functions. Both custom functions determine the cost of purchasing an item in specified quantities, but one function should return the cost to main and the other one should print the cost. Of course, the costs should be the same. Sample Output Enter the unit price 12.50 Enter the quantity 4 Please pay $50.00 Please pay $50.00

Expert Solution
Problem Analysis :
  • In this question, we will create two functions.
  • calc() will be used to calculate the final price.
  • out() will be used to print the final price.
  • In the main function, we will input base price and quantity and then call calc() with these two values.
  • Then the returned value from calc() will be passed to the out() function.
