行行好，特简单python代码检查下错误

import turtle as m
import random as c
m.screensize(1000,1000,"black")
b.{'blue','red'}
turtle.pencolor('blue')
turtle.fillcolor()
turtle.speed(64)
M=1
while M<=1000:
c=r.randint(0.50)
d=b(c)
turtle.pencolor(d)
e=1
turtle.forward(M)
turtle.right(95)
i=+1
turtle.end_fill()

代码在导入、列表使用等方面存在问题较多 ，代码这样改写即可：

import turtle 
import random as r
turtle.screensize(1000, 1000, "black")
b=['blue', 'red','cyan','green','pink']
turtle.pencolor('blue')
turtle.fillcolor()
turtle.speed(64)
M = 1
while M <= 500:
    c = r.randint(0,4)
    d = b[c]
    turtle.pencolor(d)
    turtle.forward(M)
    turtle.right(95)
    M +=1
turtle.end_fill()
turtle.done()
