Python Strings and String Manipulation: Points to remember

Points to remember:

·        String is a data type in python.

·        Strings are immutable, that means once you define string, it cannot be changed during execution.

·        Defining strings within triple quotes also allows creation of multiline strings.

·        In a String, python allocate an index value for its each character which is known as subscript.

·        The subscript can be positive or negative integer numbers.

·        Slice is a substring of a main string.

·        Stride is a third argument in slicing operation.

·        Escape sequences starts with a backslash and it can be interpreted differently.

·        The format( ) function used with strings is very versatile and powerful function used for formatting strings.

·        The ‘in’ and ‘not in’ operators can be used with strings to determine whether a string is present in another string.
