以下是我的照這課程所打出來的code
%matplotlib inline
import numpy as np
import matplotlib.pyplot as plt

from ipywidgets import interact_manual

X = np.random.rand(6)
Y = np.random.rand(6)

plt.scatter(X,Y,s=100,c="r")

X = np.linspace(0,1,1000)

def draw(n):
plt.scatter(X ,Y, s=100, c="r")
y = 0.5*np.sin(n*x*2*np.pi) + 0.5
plt.plot(x, y)
plt.show()

interact_manual(draw, n=(1., 200.))

想請問為什麼最後沒辦法跟老師一樣順利完成，反而出現ValueError: x and y must be the same size

謝謝
