Python 将类似条目分组

我有一个numpy阵列：

array([  2.86656000e+09,   2.86688000e+09,   2.86708000e+09,
     2.86860000e+09,   2.86884000e+09,   2.86908000e+09,
     2.86920000e+09,   2.87024000e+09,   2.87040000e+09,
     2.87056000e+09,   2.87076000e+09,   2.87108000e+09,
     2.87120000e+09,   2.87152000e+09,   2.87260000e+09,
     2.87272000e+09,   2.87280000e+09,   2.87448000e+09,
     2.87464000e+09,   2.87476000e+09,   2.87484000e+09])

对相似值进行分组的最佳方法是什么（例如，差值不大于1000000）？

谢谢你的回答

作为注释中链接的解决方案的替代方案，类似这样的解决方案应该可行：

In [1]: import numpy as np

In [2]: arr = np.array([  2.86656000e+09,   2.86688000e+09,   2.86708000e+09,
   ...:      2.86860000e+09,   2.86884000e+09,   2.86908000e+09,
   ...:      2.86920000e+09,   2.87024000e+09,   2.87040000e+09,
   ...:      2.87056000e+09,   2.87076000e+09,   2.87108000e+09,
   ...:      2.87120000e+09,   2.87152000e+09,   2.87260000e+09,
   ...:      2.87272000e+09,   2.87280000e+09,   2.87448000e+09,
   ...:      2.87464000e+09,   2.87476000e+09,   2.87484000e+09])

In [3]: np.split(arr, np.where(np.diff(arr) > 1000000)[0] + 1)
Out[3]: 
[array([  2.86656000e+09,   2.86688000e+09,   2.86708000e+09]),

         2.87484000e+09])]

结果应该是什么样的？您需要一组还是多组？如果有多个可以相交？事实上，我没看到。非常感谢我一直在寻找的…结果应该是什么样的？您需要一组还是多组？如果有多个可以相交？事实上，我没看到。谢谢你，正是我想要的。。。
