Welcome to Lecture 74 of the course "Programming in Python" by Prof. Sudarshan Iyengar. Full Course: https://study.iitm.ac.in/ds/course_pages/BSCS1002.html Video Overview In this lecture we continue our study of file handling in Python with a focus on using f.seek() to navigate within files and f.read() to access data. We begin with simple text file manipulation before moving on to an engaging example of searching for genetic sequences within a large human genome file. You will learn strategies to efficiently handle and analyze very large files even those that exceed memory capacity. The lecture also introduces the Knuth Morris Pratt algorithm a powerful method for substring searching in large strings. About IIT Madras' online Bachelor of Science programme IIT Madras offers four year BS programmes that aim to provide quality education to all irrespective of age educational background or location.
