6. Strings - Part B
String manipulation in Python is crucial for processing text values. Key operations include concatenation, slicing, and recognizing the immutability of strings. While strings can be combined and sections can be extracted, modifications result in new string creations rather than in-place updates.

What we have learnt
- Strings are sequences of characters used in Python to represent text.
- Strings are immutable, meaning that once a string is created, it cannot be modified in place.
- Concatenation combines two or more strings, and slicing enables extracting parts of the string.
Key Concepts
- -- String
- A sequence of characters used to represent text values in Python. There is no distinct type for a single character.
- -- Immutability
- The characteristic of strings in Python that prevents them from being modified directly; any alteration results in a new string object.
- -- Concatenation
- The operation of joining two or more strings using the '+' operator.
- -- Slicing
- Extracting a portion of the string by specifying a range of indices.
