python分割数组里面重复的元素

 1 c=[1,1,1,1,2,2,2,3,3,4,4,4,4,4,5,5,5,]
 2 a = []
 3 x = []
 4 for i in range(0,len(c)):
 5     if i + 1 < len(c):
 6         if c[i] == c[i + 1]:
 7             x.append(c[i])
 8         else:
 9             x.append(c[i])
10             a.append(x)
11             x = []
12     else:
13         x.append(c[len(c) - 1])
14         a.append(x)
15 print(a)

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