Make sure the file HouseSign. py is selected and open. You need to assign variables for the following: A variable for the cost of the sign assigned to 0.00 (charge). A variable for the number of characters assigned to 8 (numChars). A variable for the color of the characters assigned to "gold" (color). A variable for the wood type assigned to "oak" (woodType). Write the rest of the program using assignment statements and if statements as appropriate. The output statements are written for you. Execute the program by clicking the Run button at the bottom of the screen. Your output should be: The charge for this sign is $82.0. g
