                            想改善这个问题吗？ Update the question，所以它是on-topic，用于堆栈溢出。

我使用以下代码生成随机游走的y坐标。

from random import *
n = 10
length = 100*n

def ncount(vector):
    return sum(vector)
randBinList = lambda n: [randint(0,1) for b in xrange(1,n+1)]

vector = randBinList(length)

ycoords = [ncount(vector[i:i+n-1]) for i in xrange(length-n+1)]
xcoords = range(length-n+1)

如何在2d中绘制此随机游走图？

最佳答案

from pylab import *

ycoords = [ncount(vector[i:i+n-1]) for i in xrange(length-n+1)]
xcoords = range(length-n+1)

plot(xcoords,ycoords)

show()
