List is a series of scalar values separated by commas and enclosed in round brackets. A list is immutable and hence once defined, you cannot change it directly.

Example

(); # empty list

(1,2,3,4,5); # integer list

("Hello", "World"); #string list

("happy", 16) # list with different types of data

List elements can be displays using print operator like below:

print(()); # prints nothing as the list is empty
print("\n");
print(1,2,3,4,5); # prints 12345
print("\n");
print("Hello", "World"); # prints HelloWorld
print("\n");
print("happy", 16) # prints happy16

Lists are indexed like arrays and indices starts from zero, means list[0] refers to first element and to access nth element, you should use list[n-1].

print((1,2,3,4,5)[0]); # to access first element
print "\n"; 

print((1,2,3,4,5)[2]); # to access third element
print "\n"; 

print((1,2,3,4,5)[4]); # to access last element
print "\n";

qw() function

qw() function allows you to get a list by extracting words out of a string using space as a delimiter. Both gives same result.

print('Apple','Mango','Orange','Kiwi'); 
print("\n");
 
print(qw(Apple Mango Orange Kiwi)); 
print("\n");
