Welcome to Episode 6 of my Python for Bioinformatics series 🎬

In this episode, we’ll dive into strings, one of the most important data types in Python, and the backbone of bioinformatics programming.

You’ll learn:
✅ What strings are and how to define them (using DNA, RNA, gene names, and species names)
✅ How indexing works (positive & negative indexing) to access bases or amino acids
✅ String slicing for extracting codons, subsequences, or regions of interest
✅ Using step values for skipping characters and reversing sequences
✅ Concatenation (joining multiple DNA fragments into a single sequence)
✅ Why numbers can’t be directly added to strings, and how to fix it
✅ How to find the length of sequences using ‘len()’

This episode is packed with real bioinformatics-focused examples, showing how strings help us handle DNA, RNA, proteins, and gene data.

This series is designed for absolute beginners in Python for biology, helping you build a solid foundation step by step.
