Dropbox upload and share. Quick and dirty, no auth (assumes existing access token). Only tested with an app that can only access its own files, in which case the target folder is relative to the app root folder.

dropboxshare.py

#!/usr/bin/env python

# usage: 
# ./dropboxshare.py TARGET_FOLDER FILES ...
# Upload all files to the same folder. 
# Inside the folder, files are given the same name as their origin. 
# Prints a list of URLs, one on each line.

import dropbox 
from sys import argv
import os

# access token from the app console (self account) or obtained from a previous auth step.
access_token = 'ACCESS_TOKEN'

target_folder = argv[1]
files = argv[2:]

client = dropbox.client.DropboxClient(access_token)

for infile in files:
    basename = os.path.basename(infile)
    target_file = os.path.join(target_folder, basename)
    f = open(infile, 'rb')
    response = client.put_file(target_file, f)
    f.close()

    share_info = client.share(target_file, False)

    url = share_info['url']
    if url.endswith('?dl=0'):
        url = url[:-5]
    print url
