Python Programming

Part 4

Write one last function that combines these other functions together. We will do some simple calculations for the user using our functions. Consider how you might handle negative values

# function: print_answer # input: 2 numbers that you will peform the arthemetic operation on (both integers) # A plus or a minus symbol (string) # A width value (integer) # processing: Prints the 2 input numbers with the operator between them # followed by an equal sign and the result of the mathematical operation specified by the user # output: does not return anything 

Heres some sample code:

print_answer(5, 2, '+', 5) print() 

Which will generate . . .

 ***** * ***** * ***** * * ***** * * ***** * ***** * ***** ***** ***** ***** * * * * 

You can assume the height of these operators is the same as the height of your numbers (5 units).

I have created all the needed functions I just do not know how to properly combine them for this last part. Pease help! Here are all the functions. (Part I need is at the very bottom)

# function: horizontal_line # input: a width value (integer) # processing: prints a single horizontal line of the desired size # output: does not return anything  def horizontal_line(width): hline = ("*" * width) print(hline) # function: vertical_line # input: a shift value and a height value (both integers) # processing: generates a single vertical line of the desired height. the line is # offset from the left side of the screen using the shift value # output: does not return anything  def vertical_line(shift, height): for i in range(0, height): vline = (" " * shift + "*") print(vline) # function: two_vertical_lines # input: a width value and a height value (both integers) # processing: generates two vertical lines. the first line is along the left side of # the screen. the second line is offset using the "width" value supplied # output: does not return anything  def two_vertical_lines(height, width): for i in range(0, height): vline2 = ("*" + " " * (width-2) + "*") print(vline2) #------------------------------------------------------------------------------------------------  #
