Python File Access

File handling in Python indeed assumes a vital role when it comes to the persistent storage of data. This feature offers a seamless and built-in capability for creating, writing, reading, modifying, and deleting files, simplifying the management of data within a program. Python's native support for file handling obviates the necessity of importing external libraries, making it an intrinsic and integral part of the language's core functionality. In Python, file processing takes place in the following order.

  1. Open a file which returns a file handle
  2. Use the file handle to perform actions
  3. Close the file handle

With Python's file handling mechanisms, developers can effortlessly interact with files, enabling the creation of new files, writing data to them, reading from them, updating their contents, and even removing them when necessary. The simplicity and intuitiveness of Python's file handling functions streamline the process of working with files, reducing the complexity of file operations and facilitating streamlined file management.

File Access Mode

The file access mode decide the mode in which the file has to be opened for, create, read, write, append, etc. The key function for working with files in Python is the open() method. The open() method takes two arguments: filename and mode.


There are four types of mode, that Python provides and how files can be handle:

    "r", for reading.
  1. "w", for writing.
  2. "a", for appending.
  3. "r+", for both reading and writing

Python Write File

file = open('myFile.txt','w') file.write("Some thing write here..") file.close()

Python Read File

Python file operations

Python's file handling versatility caters to a wide range of file formats and data types, offering flexible options to read and write files in various contexts. The absence of external library dependencies for basic file operations enhances code readability and minimizes external dependencies, resulting in cleaner, more concise code.


Python's native file handling functionality is a powerful and convenient tool that empowers programmers to manage data persistence and seamlessly interact with files without the need for additional libraries. This built-in capability reinforces Python's status as a user-friendly and comprehensive language, making it a favored choice for file-based data operations and manipulation tasks.
