• In a computer that has internet access, create an empty folder where the required python packages will be downloaded. Let the path of the folder be C:\Users\Abcd\offline_packages\packages_folder
• Let us download a python package named flask into the folder

pip download -d "C:\Users\Abcd\offline_packages\packages_folder" flask

• In the above command, the directory location is specified using the -d flag
