Summary
- In Python, a substring is a portion of a larger string and can be extracted using slicing or string methods.
- Slicing involves specifying a start and stop index, positive or negative, to select a range of characters.
- String methods such as find(), split(), partition(), and replace() are more flexible for dynamic scenarios.
- Slicing is the best choice for simple cases and for improved performance when the indices are known.
- Combining both methods helps you write clean, efficient, and bug-free code and to master substring extraction in Python it is key to practice in real-world scenarios.
This article offers a comprehensive guide to substring extraction in Python using slicing and string methods with tips and best practices along with examples and a common pitfall to avoid.
