list - Encountering IndexError when file parsing with Python -

-

i have file containing previous tcpdump, file has lines in format:

17:20:03.867998 ip 23.222.75.204.443 > 192.168.0.15.51773: flags [.], ack 518, win 916, options [nop,nop,ts val 303057114 ecr 43022775], length 0 17:20:03.870231 ip 209.148.192.43.80 > 192.168.0.15.60174: flags [.], seq 1:1449, ack 511, win 486, options [nop,nop,ts val 1840008838 ecr 43022779], length 1448

my function extracts specific strings in each line (the source , destination addresses) , prints them. strange thing works (everything should print does) in end error.

here's code:

def parse_file() :    try :       file_object = open("tcp_dump","r")        x in file_object.readlines() :          source_ip=x.split("ip ")[1].split(" >")[0]          dest_ip=x.split("> ")[1].split(": flags")[0]          print(source_ip)          print(dest_ip)        file_object.close()     except ioerror :       print("the specified file not found/accessed")   parse_file()

here's output:

23.222.75.204.443 192.168.0.15.51773 209.148.192.43.80 192.168.0.15.60174 traceback (most recent call last):   file "./test", line 26, in <module>     parse_file()   file "./test", line 15, in parse_file     source_ip=x.split("ip ")[1].split(" >")[0] indexerror: list index out of range

java - Static nested class instance -

this question has answer here: java inner class , static nested class 23 answers i came across in java, know static nested class why create instance of 'static'. isn't whole idea of 'static' use without instance? understand concept of inner classes, why (and frankly how possible to) create 'instance' of 'static' member @ ? why this: 1- outerclass.staticnestedclass nestedobject = new outerclass.staticnestedclass(); 2- nestedobject.anestedclassmethod(); and not this: 1- outerclass outerinstance=new outerclass(); 2- outerinstance.staticnestedclass.anestedclassmethod(); use on inner classes, keyword static indicates can access inner class without instance of outer class. for example: public class outer { public static class inner { /* code here. */ } } with construction, can create instance of inn

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
