Python provides easy support to read and access the content within the file. Text files are first opened and then the content is accessed from it in the order of lines. By default, the line numbers begin with the 0th index. There are various ways to read specific lines from a text file in python, this article is aimed at discussing them.

Python offers several ways to read files. The readlines function is one of them. It allows Python to accept a text file as input and then store every line of text in the file as an element of a list. This function reads text files until it reaches the end-of-file EOF. Then, it returns the list it creates containing all the text lines as

Python readlines Function. Last modified March 26, 2025 This comprehensive guide explores Python's readlines function, a powerful method for reading files line by line. We'll cover basic usage, memory considerations, context managers, encoding handling, and best practices. Through practical examples, you'll master line-based file reading in Python.

1. Using readline Method. The readline method reads a single line from a file each time it is called. This can be useful when you want to process a file line by line without loading the entire file into memory. with open 'example.txt', 'r' as file line file. readline while line print line. strip Removes newline character line file. readline .

The readlines function in Python is a file method that reads all lines from a file and returns them as a list. Each line in the file is stored as a separate element in the list. This function is useful when you want to read the contents of a file line by line and store them in a data structure for further processing.

These functions simplify file management by handling some of the work for us, behind the scenes. We can use many of these Python functions to read a file line by line. Read a File Line by Line with the readlines Method. Our first approach to reading a file in Python will be the path of least resistance the readlines method. This method
