Python Program To Print First 10 Even Numbers Using While Loop Code When dealing with large datasets or log files in python, you may often need to extract the first n lines for analysis or processing. here’s a comprehensive guide on various methods to achieve this goal, along with practical code examples, performance considerations, and alternate approaches. In this article, i explained how to read the first line of a file in python. i discussed some important such as using the readline() method, using the next() function, and storing the remaining lines in a python list. This code defines a function that opens a file and iterates through the first n lines, printing each line after removing the trailing newline character. it’s a clean and straightforward method for accomplishing our task.
