厉害，简洁的代码，向你学习，附上我的代码，以作记录。

# -*- coding:utf-8 -*-
def triangles()
    n,i = 1,0
    L = [0,1,0]
    yield L[1:-1]
     
    while True:
        former_list = L.copy()  #将列表复制
        length = len(former_list)
        for i in range(length-1):
            L[i+1] = former_list[i] + former_list[i+1]
        L.append(0)
        yield L[1:-1]
