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.
Test your knowledge of Python string methods with this quiz. Learn about in-built functions provided by Python to operate on strings and changing the case of strings. This quiz is perfect for Python developers looking to improve their skills.
