I could develop a workaround, but this is a real hack, using bourne 
shell and the $? variable.

def scp(from_path,to_path,pwd):
    """Copy a file with scp.

    Return the exit code."""
    cmd = '/bin/sh -c "scp -q %s %s ; echo $? ; echo XXX "' 
%(from_path,to_path)
    print cmd
    child = pexpect.spawn(cmd)
    child.expect('Password:')
    child.sendline(pwd)
    child.expect("XXX")
    parts = []
    for item in child.before.split('\n'):
    if item.strip() != "":
        parts.append(item.strip())
    code = int(parts[-1])
    print "exit code:", code
    if (code != 0):
    print parts[0]
    return code

Is there a platform independent solution?
