and tofile() from the NumPy library, or the to_scv() from Pandas library. We can also use csv module functions such as writerow(). The savetxt saves a 1D or 2D array to a text file, The tofile() writes array data to a file in binary format, The writer() writes a single ...

You can also extract the data values in the form of a NumPy array with .to_numpy() or .values. Then, use the .nbytes attribute to get the total bytes consumed by the items of the array: Python >>> df.loc[:, ['POP', 'AREA', 'GDP']].to_numpy().nbytes 480 The result is...

Micro-Manager NDTiffstores multi-dimensional image data in one or more classic TIFF files. Metadata contained in a separate NDTiff.index binary file defines the position of the TIFF IFDs in the image array. Each TIFF file also contains metadata in a non-TIFF binary structure at offset 8. Do...
