python turtle库制作倒计时
1、不多废话，直接上代码
from turtle import*
from time import*
from random import*
def yesgo():
p = 20
s = pow(2,1/2)
begin_fill()
lt(45)
fd(p)
rt(45)
fd(40*s)
rt(45)
fd(p)
rt(90)
fd(p)
rt(45)
fd(40*s)
rt(45)
fd(p)
rt(135)
fillcolor(randint(25,255),randint(25,255),randint(25,255))
end_fill()
pu()
fd(60*s+5)
rt(90)
fd(5)
pd()
def nogo():
pu()
p = 20
s = pow(2,1/2)
fd(60*s+5)
rt(90)
fd(5)
pd()
def ifgo(d):
yesgo() if d in [2,3,4,5,6,8,9] else nogo()
yesgo() if d in [0,1,3,4,5,6,7,8,9] else nogo()
yesgo() if d in [0,2,3,5,6,8,9] else nogo()
yesgo() if d in [0,2,6,8] else nogo()
pu()
bk(5)
lt(90)
fd(5)
pd()
yesgo() if d in [0,4,5,6,8,9] else nogo()
yesgo() if d in [0,2,3,5,6,7,8,9] else nogo()
yesgo() if d in [0,1,2,3,4,7,8,9] else nogo()
def wait():
sleep(1)
def main():
setup(800,350,200,200)
colormode(255)
ht()
pu()
fd(-100)
pd()
st()
speed(10.4)
q = pow(2,1/2)
for i in range(5,0,-1):
ht()
tracer(False)
ifgo(i)
pu()
fd(60*q)
rt(180)
pd()
tracer(True)
wait()
clear()
tracer(False)
ifgo(0)
tracer(True)
hideturtle()
wait()
clear()
pencolor('pink')
write('完美',align='center',font=('Arial',100,'normal'))
hideturtle()
done()
main()
2、这个代码里面加了一点点花哨的东西，比如最后的'完美'，还有数字每一笔的颜色等等，这些都不重要，可以删除。
3、主要的是体会其中对于函数的运用。
