Extracting archived files

Python has different in-built modules to deal with different types of archived files. In this article we’ll talk about extracting different archived extensions (specifically .tar, .tar.gz, .tgz, .gz, .zip).
To know more about these extensions check compression and archiving.

# Importing required modules
import zipfile  # for .zip
import tarfile  # for .tar, .tar.gz, .tgz
import gzip   # for .gz 
import shutil  # for copying .gz object

# EXTENSIONS
ZIP_EXTENSION = ".zip"
TAR_EXTENSION = ".tar"
TAR_GZ_EXTENSION = ".tar.gz"
TGZ_EXTENSION = ".tgz"
GZ_EXTENSION = ".gz"

FILENAME_ERROR = "ERROR: Filename should not be empty."
UNKNOWN_FORMAT = "ERROR: Unknown file format. Can't extract."

# EXTRACTION 
def extract_file(filename, out_dir="data/"):
	"""Extract file based on file extension
	target_path: string, location where data will be extracted
	filename: string, name of the file along with extension
	"""
	if filename == "" or filename is None:
		raise Exception(FILENAME_ERROR)
	if filename.endswith(ZIP_EXTENSION):
		print("Extracting zip file...")
		zipf = zipfile.ZipFile(filename, 'r')
		zipf.extractall(out_dir)
		zipf.close()
	elif filename.endswith(TAR_EXTENSION) or \
		 filename.endswith(TAR_GZ_EXTENSION) or \
		 filename.endswith(TGZ_EXTENSION):
		print("Extracting tar file")
		tarf = tarfile.open(filename, 'r')
		tarf.extractall(out_dir)
		tarf.close()
	elif filename.endswith(GZ_EXTENSION):
		print("Extracting gz file")
		out_file = filename[:-3]
		with open(filename, "rb") as f_in:
			with open(out_file, "wb") as f_out:
				shutil.copyfileobj(f_in, f_out)
	else:
		print(UNKNOWN_FORMAT)
