Python β Substitute prefix part of List
When it is required to substitute prefix part of a list, the ‘len’ method and the ‘:’ operator is used.
Example
Below is a demonstration of the same −
my_list_1 = [15, 44, 82]
my_list_2 = [29, 77, 19, 44, 26, 18]
print("The first list is : " )
print(my_list_1)
print("The second list is : " )
print(my_list_2)
print("The first list after sorting is :")
my_list_1.sort()
print(my_list_1)
print("The first list after sorting is :")
my_list_2.sort()
print(my_list_2)
my_result = my_list_1 + my_list_2[len(my_list_1) : ]
print("The resultant list is : ")
print(my_result)Output
The first list is : [15, 44, 82] The second list is : [29, 77, 19, 44, 26, 18] The first list after sorting is : [15, 44, 82] The first list after sorting is : [18, 19, 26, 29, 44, 77] The resultant list is : [15, 44, 82, 29, 44, 77]
