One of the simplest way to download files in Python is via wget module, which doesn't require you to open the destination file.
The download method of the wget module downloads files in just one line. The method accepts two parameters: the URL path of the file to download and local path where the file is to be stored.

Personally, I prefer to use the request module for downloading files due to its combination of simplicity and power. However, your project may have constraints preventing you from using 3rd party libraries, in which case I'd use the urllib2 module for Python 2 or the urllib.

The following functions and classes are ported from the Python 2 module urllib as opposed to urllib2. They might become deprecated at some point in the future.
You can use wget which is popular downloading shell tool for that. Here is an example. Yes, definietly requests is great package to use in something related to HTTP requests.
For example, If I use the machine learning method, train a model that can recognize an image with the number bar code.
