Looking Inside the Strings
We can use indexing to get a specific character from a string or if we need to get a range of characters, then we use slices.
It is important to note that the value of the index must be an integer. In Python, indexing starts from 0.
If we try to access the string item outside the range then we will get an error Index Error.
In Python there is also the possibility of negative indexing, in this case -1 is the index of the last element, -2 is the penultimate one, and so on.
# Accessing string characters string = 'Hello, World' print('string = ', string) # Accessing the first character print(f'The first character is "{string[0]}"') # Accessing the last character print(f'The last character is "{string[-1]}"')
Ending index is

Indexing starts from 0.
