Pure python implementation of `scp`, using SFTP protocol. Depends on paramiko.

pyscp.py

def scp(sshclient, src, dest=''):
    path = os.path.abspath(os.path.expanduser(src)).rstrip('/')
    basename = os.path.basename(path)
    ftp = sshclient.open_sftp()
    if os.path.isdir(path):
        for root, dirs, files in os.walk(path):
            root = root.rstrip('/')
            dirname = os.path.basename(root)
            if root != path:
                dirname = os.path.join(basename, root.split(path)[1].strip('/'))
            try:
                ftp.mkdir(dirname)
            except: #folder exist
                pass
            for f in files:
                if pattern is None:
                    inf, outf = os.path.join(root, f), os.path.join(dirname, f)
                    ftp.put(inf, outf)
    else:
        outf = os.path.join(dest, os.path.basename(path))
        ftp.put(path, os.path.join(dest, os.path.basename(path)))
