从特定范围生成一组排序的随机数 [英] Generate a set of sorted random numbers from a specific range

问题描述

我想生成一组x个唯一的随机数，并用Python对其进行排序.例如: 范围(1000，10000) x = 100

I'd like to generate a set of x unique random numbers and sort them in Python. For example: range(1000, 10000) x = 100

我发现要导入random并使用random.randrange方法，然后循环获得100个随机数，最后对它们进行排序.

I've figured out to import random and use the random.randrange method, then loop to get 100 random numbers and in the end sort them.

但是，我不知道如何获得唯一的数字(这样就不会重复)-我应该验证每个循环吗?还是还有其他更简单的方法呢?我应该如何对它们进行排序?

However, I don't know how to get unique numbers (such that they do not repeat) - should I validate each and every loop? Or is there any other easier way how to do it? And how should I sort them?

谢谢大家！

推荐答案

使用 random.sample

numbers = random.sample(xrange(1000, 10000), 100)  # or `range` in Python 3

排序部分很容易-使用 list.sort 方法.

The sorting part is easy - use the list.sort method.

numbers.sort()

默认情况下，它将按从小到大的顺序对其进行排序，但是它采用一个可选的key参数来确定对其进行排序的方式.

By default this will sort it from smallest number to largest, but it takes an optional key argument which determines what to sort it on.

还有一个 sorted 函数，该函数不会在-位置，而是返回排序列表.

There is also a sorted function which doesn't modify a list in-place, but rather returns a sorted list.

numbers_sorted = sorted(numbers)

这还有一个可选的key参数.

This also has an optional key argument.
