In this article, I will share all kinds of Python file handling systems like reading files, writing, creating files, deleting processes and more. Stay here and read attentively to learn more and acquire knowledge in the Python file handling system. So let’s get started –

File handling of Python operations

Python supports any kind of file handling and maintains its users. It is most important to use when you need to keep a file permanently in the storage.

In python, we used 6 types of operations that can be handled by a python file.

  • Open(x)
  • Read(r)
  • Write(w)
  • Close
  • Rewrite
  • Delete

Now I will describe all of the above operations with an example below. Just follow these to know more about and practice this in your real life.

Create and Open files in Python

Python helps to open a file because this is a built-in method. Now I share how to create a file in python. It is enough to separate the name of the python file. 

Example of python file –

f = open (“newfile1.txt”)

Complete open a file then you need to save this under your .py. 

Saving system of python opening file –

f = open (“ newfile.txt”, “rt”)

Here ‘r’ for Reading and ‘t’ for text is the default values.

Closing file in python

Completed the performing operation of the file then you need to close it. For closing any file you need to use the close ( ) mode that is available in python.

Example of close methods –

f = open (“newfile.txt”, encoding = ‘utf-8’) 

# provide services file operations

f.close()

Read ( r ) file in Python

When you need to read any file under python it returns the whole text. If you want you can separate your needed characters here. By default, python used read () methods ( r )

Example of reading () file –

f = open ( “newfile.txt”, “r”) 

print(f.read(8))

Here you also read one line of the text file. Just include these codes under the .py file.

f =  open(“newfile.txt”, “r”)

print(f.readline())

Creating a file using write () methods

Create a file, here you need to write some essential elements that explain why you used to write the ( w ) mode of python. Also, declare the working process of append (a) mode in python.

Example of write () mode in python –

f = open (“newfile1.txt”, “a”)

f.write( “This file has more contents!” )

f.close()

# open file after appending : 

f = open (“newfile1.txt”, “r”)

print(f.read)

Deleting a file in python 

If you want to remove a file under your .py folder. Here you must import OS modules. It can be used os.remove()

Example of deleting a file –

import os

os.remove (“newfile1.txt”)

There are another two types of files in the python programming language. That is –

  1. Text file – This is the normal text that can open any kind of editor. Text files don’t have any encoding system. 

Example of text file of python –

  • Web standard – HTML< CSS< XML< JSON and more.
  • Documents – csv, tsv and more.
  • Source codes – Java, JavaScript, py, C, app, and more.
  • Configuration – int, reg, cfg and more.
  1. Binary file – When the file contains binary data that is called a binary file. It is not readable and uses basically a computer directory.

Example of a binary file in python – 

  • Documents – .doc, .pdf, .xls and more.
  • Database – .frm, .mdb, .accde and more.
  • Audio – .mp3, .mka, .aac, .wav and more.
  • Video – .mp4, 3gp, .avi and more.
  • Image – .png, .jpg, .gif, .bmp and more.
  • Archive file – .zip, .iso, .7z and more

File Methods in the Python

File Name Explanation of methods
Open()Open a new file
Write()Write a string data in the new file 
Writelines ()Write a listed string data in this file
Fileno()Provides an integer number of this file
Read( n )Read ‘n’ from the End of this file
Readable()When a file is readable, it provides a true value 
Readline()Read only one line of the file
Readlines()Read all lines of the file
Close ()Close the open file 
Seekable()When the file supports random access then it provides a true value
Tell()Find out the current file location
