. : Program that count the occurrences of a character in a string • 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. •
