Assigning elements to list is a common problem and many varieties of it have been discussed in the previous articles. This particular article discusses the insertion of range of elements in the list. Let’s discuss certain ways in which this problem can be solved.
Method #1 : Using extend()
This can be solved using the extend function in which the insertion of range of numbers can be done on the rear end using the range function.
# Python3 code to demonstrate # Assigning range of elements to List # using extend() # initializing list test_list = [3, 5, 6, 8] # printing original list print("The original list : " + str(test_list)) # using extend() # Assigning range of elements to List test_list.extend(range(6)) # print result print("The list after adding range elements : " + str(test_list)) |
The original list : [3, 5, 6, 8] The list after adding range elements : [3, 5, 6, 8, 0, 1, 2, 3, 4, 5]
Method #2 Using * operator
This problem can also be solved using the * operator and with the advantage of flexibility of addition of elements at any position.
# Python3 code to demonstrate # Assigning range of elements to List # using * operator # initializing list test_list = [3, 5, 6, 8] # printing original list print("The original list : " + str(test_list)) # using * operator # Assigning range of elements to List res = [3, 5, *range(6), 6, 8] # print result print("The list after adding range elements : " + str(res)) |
The original list : [3, 5, 6, 8] The list after adding range elements : [3, 5, 0, 1, 2, 3, 4, 5, 6, 8]
