如何在Python中就地对整数数组进行排序? [英] How to sort an integer array in-place in Python?

问题描述

如何在Python 2.6中就地对整数数组(不是列表)进行排序?标准库之一中是否有合适的功能?

how can one sort an integer array (not a list) in-place in Python 2.6? Is there a suitable function in one of the standard libraries?

换句话说，我正在寻找一个可以执行以下操作的函数:

In other words, I'm looking for a function that would do something like this:

>>> a = array.array('i', [1, 3, 2])
>>> some_function(a)
>>> a
array('i', [1, 2, 3])

提前谢谢！

推荐答案

好吧，您不能使用array.array来做到这一点，但是可以使用numpy.array:

Well, you can't do it with array.array, but you can with numpy.array:

In [3]: a = numpy.array([0,1,3,2], dtype=numpy.int)

In [4]: a.sort()

In [5]: a
Out[5]: array([0, 1, 2, 3])

或者您可以直接从array.array进行转换:

Or you can convert directly from an array.array if you have that already:

a = array.array('i', [1, 3, 2])
a = numpy.array(a)
