The *
operator can be applied between a list and an integer, to duplicate the list
the specified number of times.
Syntax
list * no_of_times_to_replicate
>>> numbers = [1, 2, 3, 4]
>>> numbers_twice = numbers * 2
>>> numbers_thrice = numbers * 3
>>>
>>> numbers
[1, 2, 3, 4]
>>>
>>> numbers_twice
[1, 2, 3, 4, 1, 2, 3, 4]
>>>
>>> numbers_thrice
[1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4]
Above snippet
demonstrates the use of the * operator for list replication.
numbers
= [1, 2, 3, 4]
This line
creates a list named numbers containing the elements 1, 2, 3, and 4.
numbers_twice
= numbers * 2
This line
replicates the numbers list two times. The * operator, when used with a list
and an integer, creates a new list by repeating the original list the number of
times specified by the integer. Here, numbers * 2 results in [1, 2, 3, 4, 1, 2,
3, 4]. The list numbers is repeated twice, and this new list is assigned to the
variable numbers_twice.
numbers_thrice
= numbers * 3
Similarly,
this line replicates the numbers list three times. The expression numbers * 3
produces [1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4]. The original list is repeated
three times, and this new concatenated list is stored in the variable
numbers_thrice.
In summary, the * operator is used to create
larger lists by repeating the contents of an existing list a specified number
of times. This snippet demonstrates creating two new lists, one with the
elements of the original list repeated twice and the other repeated thrice.
