Using Python to Analyze Genomic Data for Personalized Medicine
Using Python to Analyze Genomic Data for Personalized Medicine

Simply put, in layman's language, this topic means combining the language of life with the language of programming. It is well-known that Python is a universal language that fits any business and industry. Now it's time to encode the mysteries of our genetic system and how a programming language can help the medical world make personalized medicine.
Genomic Data: The human body comprises cells that enable its functions. When these cells come together, they form an organism called the Genome, which holds all the genomic data. When you look at it closely, genomic data plays a crucial role in numerous human diseases. This is where the concept of personalized medicine has emerged because every human has different Genomic data, and it's possible that one medicine can act differently on two humans.
At the time of COVID-19, the same set of medicines was working on one category of patients while the same set of medicines was working differently on other patients. Personalized medicine is a solution to this challenge. To overcome this challenge, the hospitals or medicine industry can approach an IT Firm or a Python development company where they can easily consult and hire Python developers.
Understanding Personalized Medicine
Personalized medicine aims to customize healthcare, with medical decisions tailored to the individual patient. This approach considers genetic variations that affect how patients respond to treatments, allowing for more effective and targeted therapies. The primary goal is to improve patient outcomes by providing the right treatment at the right time.

How to handle large datasets in Python that don't fit into memory?
Aug 14, 2025 pm 01:00 PM
When processing large data sets that exceed memory in Python, they cannot be loaded into RAM at one time. Instead, strategies such as chunking processing, disk storage or streaming should be adopted; CSV files can be read in chunks through Pandas' chunksize parameters and processed block by block. Dask can be used to realize parallelization and task scheduling similar to Pandas syntax to support large memory data operations. Write generator functions to read text files line by line to reduce memory usage. Use Parquet columnar storage format combined with PyArrow to efficiently read specific columns or row groups. Use NumPy's memmap to memory map large numerical arrays to access data fragments on demand, or store data in lightweight data such as SQLite or DuckDB.
