Unable to get whole firewall policy index

[anonymous1120]

hi everyone,
i'm trying to extract all the firewall policies with 2k+ index. However, i'm only getting around 1.7k+ index on .txt file. here's the sample code we use.

    os.chdir(os.path.dirname(__file__))
    with open("output", "w") as file:
        policyCommand = device.op("<show><running><security-policy></security-policy></running></show>", cmd_xml=False)
        
        if policyCommand.attrib['status'] == "success":
            file.writelines((policyCommand[0].find('member').text))

        else:
            print(f"Connecting Error")
