Want to Download contents of a folder

You have 2 options:

Download the folder as a zip file:

from boxsdk import JWTAuth, Client
def main():
    auth = JWTAuth.from_settings_file('.jwt.config.json')
    auth.authenticate_instance()
    client = Client(auth)
    folder_id = '163422716106'
    user = client.user().get()
    print(f"User: {user.id}:{user.name}")
    folder = client.folder(folder_id).get()
    print(f"Shared Folder: {folder.id}:{folder.name}")
    print("#" * 80)
    print("Type\tID\t\tName")
    items = folder.get_items()
    
    download_items=[]
    for item in items:
        print(f"{item.type}\t{item.id}\t{item.name}")
        download_items.append(item)
    
    print("#" * 80)
    
    with open(folder.name+'.zip', "wb") as download_file:
        status = client.download_zip(folder.name, download_items, download_file)
    
    print(f"Download status: {status}")

if __name__ == "__main__":
    main()
    print("Done")

Resulting in:

(file in folder 15M Feb  3 10:21 Box UI Elements Demo.zip)

The other option is to recursively download each item one by one:

import os
from boxsdk import JWTAuth, Client

def main():
    auth = JWTAuth.from_settings_file('.jwt.config.json')
    auth.authenticate_instance()
    client = Client(auth)
    folder_id = '163422716106'
    user = client.user().get()
    print(f"User: {user.id}:{user.name}")
    folder = client.folder(folder_id).get()
    print(f"Downloadin folder: {folder.id}:{folder.name}")
    print("#" * 80)
    print("Type\tID\t\tName")
    os.chdir('downloads')
    
    items = folder.get_items()
    download_items(items)
    os.chdir('..')

def download_items(items):
    for item in items:
        if item.type == 'folder':
            os.mkdir(item.name)
            os.chdir(item.name)
            download_items(item.get_items())
            os.chdir('..')
        if item.type == 'file':
            print(f"{item.type}\t{item.id}\t{item.name}",end='')
            with open(item.name,'wb') as download_file:
                item.download_to(download_file)
            print("\tdone")

if __name__ == "__main__":
    main()
    print("Done")

Resulting in:
