String Basics#

Strings are one of Python's most commonly used data types. They are immutable sequences of Unicode characters — once created, their content cannot be changed. Python offers powerful built-in methods for searching, formatting, slicing, and transforming text.

String Checking#

String checking methods return True or False and are useful for input validation, parsing, and conditional logic.

String Operations#

Beyond basic methods, Python provides tools for padding and aligning text, translating characters, encoding strings to bytes, and pattern matching with regular expressions. These operations cover most real-world text processing tasks using only the standard library.
