Python循环画棋盘

import turtle

t = turtle.Pen()
t.speed(0)
geZi = 11    # 格子数量
kuanDu = 10  # 格子宽度
changDu = geZi*kuanDu   # 棋盘总宽度
# 画横线，格子数量+1
for i in range(geZi + 1):
    t.penup()
    t.goto(-changDu, changDu - i * kuanDu)
    t.pendown()
    t.goto(0, changDu - i * kuanDu)
# 画竖线，格子数量+1
for i in range(geZi + 1):
    t.penup()
    t.goto(-changDu + i * kuanDu, changDu)
    t.pendown()
    t.goto(-changDu + i * kuanDu, 0)

turtle.done()
