String method
A string method is a callable operation provided by a programming language or library for inspecting, transforming, or otherwise processing string values.

A string method is an operation provided by Python's string type for inspecting or producing text values.
- How it is used
- Uses string methods to inspect, search, format, and modify text while reading Python code.
- How deep it goes
- Defines method-call syntax and demonstrates common operations, but stops short of implementation internals.
- Examples
- Demonstrates case, digit, and alphanumeric checks, phone-number cleaning, and replacing a found word in text.
- What you can do after
- Apply it via Python to test, search, format, and clean strings, then request more precise explanations of unfamiliar methods.

Operations provided by the Python string type for inspecting, transforming, and manipulating textual values.
- How it is used
- Applies textual operations to pandas Series through the str accessor during data preparation and analysis.
- How deep it goes
- Explains returned Series, common operations, Boolean filtering, and custom functions without descending into string-object internals.
- Examples
- Demonstrates lengths, digit tests, pattern matching, Boolean selection, replacement, and one-hot categorical expansion.
- What you can do after
- Apply string methods through str, assign returned Series, filter matching values, and create transformed or indicator columns.
