"我无法绘制规则 30"

Question

当我阅读这个<\/a>答案时，我进行了测试，但是这段代码什么也没做，这可能已经过时了。 有没有新功能之类的？

代码<\/h2>

def rule(t): return t[0] ^ (t[1] or t[2]) def initial_state(width): initial = [0]*width if width%2: initial[width \/\/ 2] = 1 else: initial.insert(width\/\/2, 1) return initial def get_triples(l): return zip(l,l[1:],l[2:]) def rule30(l): return [rule(t) for t in get_triples([0] + l + [0])] def apply_rule(width): rv = [initial_state(width)] while not rv[-1][0]: rv.append(rule30(rv[-1])) return rv ## This does not work import matplotlib.pyplot as plt plt.figure(figsize=(10,6)) plt.imshow(apply_rule(250), cmap='hot')<\/code><\/pre>"
