PYTHON TURTLE GRAPHICS - Write a program that draws a checkerboard. The lower left corner should be at position 0,0 and the board should be red and black, with each square being 20 pixels in size. The lower left corner should be black, and the pattern should consist of alternating black and red squares, for a total of 64 squares in an 8x8 pattern. (Listed below is the thought process). Please provide source code as well as output in Turtle. Thanks.
Define a function drawASquare(color)
Put the pen at the position (0,0)
For each row:
For each square:
If the sum of the row number and square number is even:
drawASquare(black)
Else:
drawASquare(red)
