We can only use the integer number type for indexing; otherwise, the TypeError will be raised. Example: String1 = ‘intellipaat’ print (String1) print (String1[0]) print (String1[1]) print (String1[-1]) Output: Intellipaat i n t Python is one of the most demanding skills right ...
To access tuple items we use indexes. Tuple indexes arezero-based, so the first element of a non-empty tuple is alwaystuple[0]. We can use the index operator[]to access an item in a tuple. Note: TypeError: If you do not use integer indexes in the tuple. For example, tuple_data[...
