python分割数组里面重复的元素

c=[1,1,1,1,2,2,2,3,3,4,4,4,4,4,5,5,5,]
a = []
x = []
for i in range(0,len(c)):
    if i + 1 < len(c):
        if c[i] == c[i + 1]:
            x.append(c[i])
        else:
            x.append(c[i])
            a.append(x)
            x = []
    else:
        x.append(c[len(c) - 1])
        a.append(x)
print(a)

运行结果：

[[1, 1, 1, 1], [2, 2, 2], [3, 3], [4, 4, 4, 4, 4], [5, 5, 5]]
