This article mainly shows you "python how to randomly sample elements from list", the content is easy to understand, clear, hope to help you solve doubts, the following let Xiaobian lead you to study and learn "python how to randomly sample elements from list" this article.

How to randomly sample elements from list

Import randomall_data = [num for num in range (100)] sample_data = random.sample (all_data, 20) print sample_data# [71, 25, 58, 79, 70, 69, 93, 29, 11, 30, 40, 81, 12, 48, 91, 21, 83, 42, 38, 31]

Here, 20 elements are randomly sampled from 100 elements. As you can see, the sampling function can be easily realized with the help of the sample function of random module. Python random module is very interesting, you can see if you are interested, can achieve a lot of interesting functions. For example, you can easily achieve the "shuffle" function:

Import randomorder_list = range (10) print order_list# [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] random.shuffle (order_list) print order_list# [3, 5, 9, 0, 8, 7, 1, 2, 6, 4] are all the contents of the article "how python randomly samples elements from list".
