#code

import turtle

#creating a turtle, setting max speed
t=turtle.Turtle()
t.speed(0)

#number of columns, rows
cols=5
rows=5
#size of each square
size=60

#starting position
x=-150
y=150
#pen up
t.up()
#initial color - black
color='black'
#looping through each row and column
for i in range(rows):
    for j in range(cols):
        #moving turtle to x,y
        t.goto(x, y)
        #using current color as fill color
        t.fillcolor(color)
        #start to fill
        t.begin_fill()
        #filling a rectangular path
        t.forward(size)
        t.right(90)
        t.forward(size)
        t.right(90)
        t.forward(size)
        t.right(90)
        t.forward(size)
        t.right(90)
        #end of fill
        t.end_fill()
        #moving x size spaces forward
        x+=size
        #swapping colors between black and white
        if color=='black':
            color='white'
        else:
            color='black'
    #resetting x to starting position
    x=-150
    #updating y size spaces down
    y-=size

#hiding turtle and finishing drawing
t.ht()
turtle.done()

#output
