TypeError: can only concatenate str (not "Ether") to str

I working in Google Colab. I have pcap file (Network packet traffic of IoT sensors) and I want to extract the features from these packets and save it as csv file to start train machine learning algorithms. I install tshark. but I'm still have this problem (TypeError: can only concatenate str (not "Ether") to str) the error in line

  tsharkcommand = ("tshark -r" + xx +"-T fields -e ip.len -e ip_hdr_len")

import glob 
import os 

filey = open("try.csv",'a')
filey.writelines("Lable,IPlength,DestIP")
packets = rdpcap("bruteforce.pcapng")

for xx in packets:
  all = str (os.popen(tsharkcommand).read())
  all = all.splitlines()

  for features in all:
      filey.writelines("Lable"+ "," + features + "\n")

how can I solve that? and if you have any way to extract features easier than this way, please provide me.

From what I could figure out of your code you're trying to run the tshark command using the infile option to get ip.len and ip_hdr_len out of the input file.

However, scapy.all.rdpcap() doesn't return a file but instead returns packets[Packet] object type which is not suited for your purpose.

You can instead use xx.fields.values() to get the src.ip, dst.ip, ip.length of each packet in the pcap file
