Read FASTA Files in Python | Bioinformatics Made Easy

🧬 Reading FASTA Files with Python 💻

In bioinformatics, DNA and protein data is often stored in FASTA files, one of the most widely used formats in genomics and proteomics.

In this short tutorial, we break down:
✔️ What a FASTA file looks like (headers + sequences)
✔️ How to read it line by line using Python
✔️ How to separate sequence IDs from the DNA sequence
✔️ Printing the results in a clean format

This simple method is the foundation of many bioinformatics workflows, from sequence analysis, alignment, and genome assembly to protein studies.

Whether you’re a beginner in bioinformatics or practicing Python for life sciences, this is a great starting point to understand how data is structured and processed.
