Uhm, it was so easy ;)

part of my python script now

    os.system("tc qdisc del root dev %s 2> /dev/null" % ppp_iface)
    os.system("tc qdisc del dev %s ingress 2> /dev/null" % ppp_iface)
    
    # downstream
    os.system("tc qdisc add dev %s root tbf rate %skbit latency 50ms burst 1540"
              % (ppp_iface, speed_down))
    
    # upstream
    os.system("tc qdisc add dev %s handle ffff: ingress" % ppp_iface)
    os.system("tc filter add dev %s parent ffff: protocol ip prio 50 u32 match ip src 0.0.0.0/0 police rate %skbit burst 10k drop flowid :1" % (ppp_iface, speed_up))
