[Tutor] Turtle color question

[Roger Lea Scherer]

I've tried everything I can think of but cannot get the pencolor to change.
(Although the arrow drawing the boxes changes color.) I've placed it in
places I didn't even think it would work. The arrow draws what looks like
the boxes I expect, but the color looks the same as the background. So I
assigned a variable and printed that variable which says None. See:

 RESTART: C:/Users/Roger/AppData/Local/Programs/Python/Python36/turtle
square draw.py
None
>>>

Removing " color = " doesn't change the outcome. I hope this adequately
explains things.Thanks, again.

​import turtle

def drawSquare(t, sz):
    """Get turtle t to draw a square of sz side"""
    t.pu()
    t.forward(sz*2)

    for i in range(4):
        t.forward(sz)
        t.left(90)


wn = turtle.Screen()
wn.bgcolor("blue")

alex = turtle.Turtle()
color = alex.pencolor("darkgreen")
print(color)

def main():
    for i in range(4):
        drawSquare(alex,20)

main()

wn.exitonclick()
