    Study Notes

    Python Strings

    • A Python string is a sequence of characters enclosed in quotes (either single quotes or double quotes) used to represent textual data.

    String Operations

    • The time complexity for changing the case of Python strings (e.g., upper(), lower(), title(), etc.) is O(n), where n is the length of the string, because each character in the string needs to be processed.

    • The auxiliary space complexity for changing the case of Python strings is O(n), as a new string is created with the modified case.

    String Methods

    • A Python string method is a function that can be used to manipulate and analyze a string.

    • Python string methods are best described as immutable, meaning they do not modify the original string but instead return a new string with the modifications.
