python-scipyHow can I use Python and Numpy to zip files?

Python and Numpy can be used to zip files in a few different ways.

One way is to use the shutil library to compress a file into a zip archive. This library provides a function called make_archive which can be used to create a zip archive.

Example code

import shutil

shutil.make_archive('my_zip_file', 'zip', 'C:\\path\\to\\folder')

This code will create a zip archive named my_zip_file.zip in the current working directory, containing the contents of the folder located at C:\\path\\to\\folder.

Another way to create a zip archive is to use the zipfile library. This library provides a function called ZipFile which can be used to create a zip archive.

Example code

import zipfile

zf = zipfile.ZipFile('my_zip_file.zip', 'w')
zf.write('C:\\path\\to\\file.txt')
zf.close()

This code will create a zip archive named my_zip_file.zip in the current working directory, containing the file located at C:\\path\\to\\file.txt.

Finally, Numpy can be used to zip files by using the savez function. This function can be used to save multiple arrays into a single zip archive.

Example code

import numpy as np

a = np.array([1,2,3])
b = np.array([4,5,6])

np.savez('my_zip_file.npz', a=a, b=b)

This code will create a zip archive named my_zip_file.npz in the current working directory, containing the two arrays a and b.

In summary, Python and Numpy can be used to zip files by using the shutil.make_archive function, the zipfile.ZipFile function, or the np.savez function.
