Each HDF5 file has an internal structure that allows you to search for a specific dataset. You can think of it as a single file with its hierarchical structure, just like a collection of folders and subfolders. By default, the data is stored in binary format, and the library is compatible...

In this step-by-step tutorial, you'll learn about MATLAB vs Python, why you should switch from MATLAB to Python, the packages you'll need to make a smooth transition, and the bumps you'll most likely encounter along the way.
It is convenient to have a mechanism that allows us to save the processed data for future retrieval without going through the same costly process again. Pickle is a utility that allows us to save Python objects in a binary file. In other words: Pickle allows us to save time. Here, we ...
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...

Note: Python does not provide a powerful method to propagate metadata to data frames. For example, operating such asgroup_byon a data frame with attached metadata will return the previous data frame without attached metadata. However, you can store the metadata in anHDF5file for later processing...
