access all packets from Pcap file

Question

I am trying to access some information from pcap file. I am able to do for a single packet, and pcap file have multiple packet.

I coded this into Django.

What should I add into this code by which it return all packet information

testcap = open("Test_1.pcap")
capfile = savefile.load_savefile(testcap, verbose=True)

for i in range(len(capfile.packets)):

    ip_packet = ip.IP(binascii.unhexlify(ethernet.Ethernet(capfile.packets[i].raw()).payload));
    mac_packet = ethernet.Ethernet(capfile.packets[i].raw());
    packet = capfile.packets[i];



def index(request):
    answer = [

             str(packet.timestamp),
             str(packet.packet_len),
             str(mac_packet.src),
             str(mac_packet.dst),
             str(ip_packet.src),
             str(ip_packet.dst),
              ]

    return HttpResponse("<br>" . join(answer))

I tried for looping also still its not working.
