Perl | values() Function
  • Last Updated : 07 May, 2019

values() Function in Perl returns the list of all the values stored in a Hash. In a scalar context it returns the number of elements stored in the Hash.

Note: Values returned from the value() Function may not always be in the same order.

Syntax: values Hash

Returns: list of values in the list context and number of values in the scalar context

Example 1:






#!/usr/bin/perl -w
  
# Hash containing Keys and values
%sample_hash = ('Geeks' => 'A',
                'for' => 'B',
                'Geek' => 10,
                'World' => 20);
  
# values() in list context returns 
# values stored in the sample_hash
@values = values(%sample_hash);
print("Values in the Hash are: "
       join("-", @values), "\n");
  
# values() in scalar context returns
# the number of values stored in sample_hash
$values = values( %sample_hash);
print "Number of values in Hash are: $values";
Output:
Values in the Hash are  A-B-10-20
Number of values in Hash are: 4

Example 2:




#!/usr/bin/perl -w
  
# Hash containing Keys and values
%sample_hash = (1 => 'Welcome',
                2 => 'to',
                3 => 'Geeks',
                4 => 'World');
  
# values() in list context returns 
# values stored in the sample_hash
@values = values( %sample_hash);
print("Values in the Hash are ",
      join("-", @values), "\n");
  
# values() in scalar context returns
# the number of values stored in sample_hash
$values = values(%sample_hash);
print "Number of values in Hash are: $values";
Output:
Values in the Hash are  Welcome-World-to-Geeks
Number of values in Hash are: 4
