In Python’s main zipfile module using python unzip zip object, ZipFile class supports a member function to extract all the data contents from a ZIP archive with python unzip file in memory,
ZipFile.extractall(path=None, members=None, pwd=None)
It accepts bellow some arguments : like as a “python unzip file with password”.
- path : main root location path where zip file required to be all data extracted files and folder, if not supported it will extract the data contents in ongoing directory.
- members : here some example of member list of files to be extracted as well as python unzip list of tuples. It will extract all the data files in zip if this parameters is not supported.

with ZipFile('pakainfoDir.zip', 'r') as zipObj:
# fetch a list of all the main folder archived file names from the zip
listOfFileNames = zipObj.namelist()
# Iterate over the file names
for fileName in listOfFileNames:
# Check filename endswith csv
if fileName.endswith('.csv'):
