csv

问题 I want to end each interation of a for loop with writing a new line of content (including newline) to a csv file. I have this: # Set up an output csv file with column headers with open('outfile.csv','w') as f: f.write("title; post") f.write("\n") This does not appear to write an actual \n (newline) the file.

问题 I was wondering if there is any tool that can parse pcap data and convert it to a csv file with the following information: timestamp, bytes, uplink/downlink, some extra info.. Basically, the uplink/downlink could be seen by the IP/MAC address, and the extra info is not really needed, but what I mean with that is choose a specific field of a packet for example.
