各位,我遇到了这个错误能指导一下我吗?
'RandomWalk' object has no attribute 'x_values'
from random import choice
class RandoWalk():
"""一个生成随机漫步数据的类"""
def __init__(self,num_points = 500):
self.nun_points = num_points
#所有随机漫步都始于(0,0)
self.x_values = [0]
self.y_values = [0]
def fill_walk(self):
while len(self.x_values) < self.num_points:
#决定前进方向
x_direction= choice([1, -1])
x_distance = choice([0,1,2,3,4])
x_step = x_direction * x_distance
y_direction= choice([1, -1])
y_distance = choice([0,1,2,3,4])
y_step = y_direction * y_distance
#拒绝原地踏步
if x_step == 0and y_step == 0:
continue

next_x = self.x_values[-1] + x_step
next_y = self.y_values[-1] + t_step
self.x_values.append(next_x)
self.y_balues.append(next_y)
rw = RandomWalk()
rw.fill_walk()
plt.scatter(rw.x_values,rw.y_values,s = 15)
plt.show()
最后报错现实这个错误
