Python File Handling – Complete Study
Notes
Introduction
File handling is an important concept in Python programming that allows programs to read
data from files and write data to files. Many real-world applications store information in
files so that the data can be reused later.
In Python, file handling makes it possible to work with different types of files such as text
files, CSV files, and log files. Programs often read data from files for processing or save
program results into files for future use.
Understanding file handling is essential for developers working with data processing,
reporting systems, and automation tasks where information must be stored permanently.
Definition
File handling in Python refers to the process of creating, opening, reading, writing, and
closing files using Python programs.
Python provides built‑in functions that allow developers to work with files easily. The most
commonly used function is the open() function which opens a file and returns a file object.
Once a file object is created, programmers can perform various operations such as reading
the contents of the file, writing new information, or appending additional data.
Types of Files in Python
In Python programming, files are generally categorized into two main types: text files and
binary files.
Text files store data in the form of readable characters. Examples include .txt, .csv, and .json
files.
Binary files store data in binary format and are typically used for images, videos, or
compiled program files.
Opening Files
Before performing any operation on a file, the file must first be opened using the open()
function.
