How perl randomly extracts elements from an array
This article will explain in detail how perl randomly extracts elements from an array. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.
The shuffle subroutine in the List::Util module is used here. The List::Util module is a module dedicated to processing list data in Perl.
The methods are as follows:
Use List::Util qw (shuffle); my @ shuffled_nums = shuffle (1.. 10); # 3 9 8 5 6 4 1 10 2 7 my @ shuffled_name = shuffle ('Aids.. my$a'); # F E G A B D (my$a) = @ shuffled_name; # F
The function of shuffle () is to sort the elements in the list randomly, and we take the first value, which is equivalent to extracting an array element at random.
