How to Unpack a PKL File in Python

How to uncompress a “.tar.gz” file using Python ?

Last Updated : 17 Dec, 2020

.tar.gz files are made by the combination of TAR packaging followed by a GNU zip (gzip) compression. These files are commonly used in Unix/Linux based system as packages or installers. In order to read or extract these files, we have to first decompress these files and after that expand them with the TAR utilities as these files contain both .tar and .gz files.

In order to extract or un-compress “.tar.gz” files using python, we have to use the tarfile module in python. This module can read and write .tar files including .gz, .bz compression methods.

Approach

Import module
Open .tar.gz file
Extract file in a specific folder
Close file

File in use

Name: gfg.tar.gz

Link to download this file: Click here

Contents:

“gfg.tar.gz” file

Example:

Python3

# importing the "tarfile" module 
import tarfile 
  
# open file 
file = tarfile.open('gfg.tar.gz') 
  
# extracting file 
file.extractall('./Destination_FolderName') 
  
file.close() 

Output:

A folder named “Destination_Folder” is created.

Files are uncompressed inside the “Destination_Folder”

Example: Printing file names before extracting

Python3

# importing the "tarfile" module 
import tarfile 
  
# open file 
file = tarfile.open('gfg.tar.gz') 
  
# print file names 
print(file.getnames()) 
  
# extract files 
file.extractall('./Destination_FolderName') 
  
# close file 
file.close() 

Output:

Example : Extract a specific file

Python3

# importing the "tarfile" module 
import tarfile 
  
# open file 
file = tarfile.open('gfg.tar.gz') 
  
# extracting a specific file 
file.extract('sample.txt', './Destination_FolderName') 
  
file.close() 

Output:

A new folder named “Destination_FolderName” is created

‘sample.txt’ is uncompressed inside the “Destination_FolderName”
