  • Last Updated : 07 Jun, 2019

Shutil module in Python provides many functions of high-level operations on files and collections of files. It comes under Python’s standard utility modules. This module helps in automating process of copying and removal of files and directories.

shutil.unregister_unpack_format() method in Python is used to unregister or remove an unpack format from the list of available supported unpack format.

We can also register a new format or specify own function for unpacking existing formats using shutil.register_unpack_format() method or get the list of all supported available unpack format using shutil.get_unpack_formats() method.

Syntax: shutil.unregister_unpack_format(name)

Parameter:
name: A string representing the name of the unpack format which is to be removed from the list.



Return Type: This method does not return any value.

Code: Use of shutil.unregister_unpack_format() method




# Python program to explain shutil.unregister_unpack_format() method  
    
# importing shutil module 
import shutil
  
# Get the list of 
# supported unpack formats
formats = shutil.get_unpack_formats()
  
# Print the list
print("Supported unpack formats:")
print(formats, "\n")
  
# Remove an unpack format
name = "gztar"
shutil.unregister_unpack_format(name)
print("%s unpack format unregistered successfully." %name, "\n")
  
# Get the list of 
# supported unpack formats
formats = shutil.get_unpack_formats()
  
# Print the list
print("Supported unpack formats:")
print(formats, "\n")
Output:

Supported unpack formats:
[(‘bztar’, [‘.tar.bz2’, ‘.tbz2’], “bzip2’ed tar-file”), (‘gztar’, [‘.tar.gz’, ‘.tgz’], “gzip’ed tar-file”), (‘tar’, [‘.tar’], ‘uncompressed tar file’), (‘xztar’, [‘.tar.xz’, ‘.txz’], “xz’ed tar-file”), (‘zip’, [‘.zip’], ‘ZIP file’)]

‘gztar’ unpack format unregistered successfully.

Supported unpack formats:
[(‘bztar’, [‘.tar.bz2’, ‘.tbz2’], “bzip2’ed tar-file”), (‘tar’, [‘.tar’], ‘uncompressed tar file’), (‘xztar’, [‘.tar.xz’, ‘.txz’], “xz’ed tar-file”), (‘zip’, [‘.zip’], ‘ZIP file’)]
