2. Strings are stored as sequences of characters indexed by integers, starting at zero.

3. To extract a substring, use the slicing operator s[i:j].

4. Strings are concatenated with the plus (+) operator:
     g = a + " This is a test"

5. To perform mathematical calculations, strings first have to be converted into a numeric
    value using a function such as int() or float(). For example:
    z = int(x) + int(y) # z = 79 (Integer +)

6. Non-string values can be converted into a string representation by using the str(),
     repr(), or format() function.
