Also, the Python-based Django Framework runs Instagram and many other websites. On the science and engineering side, the data to create the 2019 photo of a black hole was processed in Python, and major companies like Netflix use Python in their data analytics work. There is also an ...
Even better, since chunked data is stored in nice uniformly sized packets of bytes, you can apply all kinds of operations to it when writing or reading from the file. For example, this is how compression works in HDF5; on their way to and from the disk, chunks are run through a compre...
