sniffing long packets with Scapy and python 3

I am sniffing packets, specificity http packets with html code using Scapy and I have noticed that some of the information is cut.
for example, I sniffed a packet from a http based website. this is the Raw layer's load:

this is the code I am using:

fileNum = 0;

def handlePacket(pkt):
    if pkt.haslayer(Raw) and pkt[Raw].load:#has content
        if str(pkt[Raw].load).find("<html") != -1:#content is html
            print('a')
            f = open(outDir+'/'+str(fileNum)+'.txt','wb')#save file
            f.write(pkt[Raw].load)
            f.close()
sniff(prn = handlePacket)

and the content just ends there.
(I know that I am currently not getting all of it because there is more html code in the website).
Why aren't I getting all of the code and How do I get the rest of the code?
