Hm. I'm not entirely sure as I don't have pygame to test your code on,
but this strikes me as odd: you're blitting the x loop once for every
iteration of the y loop. Shouldn't the two loops be at the same
indentation?

I think you perhaps want to offset one of the lines. Currently, you're
running x from 0 up, and y from 0 up, so you're drawing the (0,0) cell
twice. If you add 1 to one of them, you should be able to draw all
four walls correctly. Alternatively, leave this as it is, and just add
one more draw at (WIDTH, HEIGHT) to fill in the last square.
