In Python, indexes are used to access specific elements within a list, tuple, or string. An explicit index is a specific numerical value that is used to access a particular element in a sequence.
Here's an example:
my_list = [10, 20, 30, 40, 50]print(my_list[2]) # Output: 30 |
In this example, 2 is an explicit index that is used to access the third element (index 2) of the my_list list.
You can also use explicit indexes to modify elements in a sequence:
my_list = [10, 20, 30, 40, 50]my_list[1] = 25print(my_list) # Output: [10, 25, 30, 40, 50] |
In this example, we use an explicit index of 1 to modify the second element of the my_list list from 20 to 25.
It's important to note that if you use an index that is out of range, you'll get an IndexError:
my_list = [10, 20, 30, 40, 50]print(my_list[10]) # Output: IndexError: list index out of range |
