Recommend adding example to tarfile documentation to provide example of writing a tarfile to stdout.


files = [(file_1, filename_1), (file_2, filename_2)]

with, mode = 'w|gz') as tar:
    for file, filename in files:
        file_obj = io.BytesIO() #starts a BytesIO object
        file_obj.write(file.encode('utf-8')) #writes the file to the BytesIO object
        info = tarfile.TarInfo(filename) #creates the TarInfo #goes to the beginning of the BytesIO object else it won't write
        info.size = len(file) #sets the length of the file
        tar.addfile(info, fileobj=file_obj) #writes the tar to stdout.
