TarFile.addfile(tarinfo, fileobj=None) Add the TarInfo object tarinfo to the archive. If fileobj is given, it should be a binary file, and tarinfo.size bytes are read from it and added to the archive. You can create TarInfo objects directly, or by using gettarinfo(). TarFile.get...

I would like to numpy.load an ndarray from a file within a tar archive, without extracting to disk, in Python3. import os import numpy import tarfile # create a test tar archive a = numpy.random.rand(10, 4) numpy.save('a.npy', a) with open('foo.txt', 'w') as f: f.write(...
Sometimes you have a ZIP file and need to read the content of a given member file without extracting it. To do that, you can use .read(). This method takes a member file’s name and returns that file’s content as bytes: Python >>> import zipfile >>> with zipfile.ZipFile("sam...
read() open() takes a filename and a mode as its arguments. r opens the file in read only mode. To write data to a file, pass in w as an argument instead: Python with open('data.txt', 'w') as f: data = 'some data to be written to the file' f.write(data) In the...
