QUESTION
I am new to kafka and zookepper, and I am trying to create a topic, but I am getting this error -
...ANSWER
Answered 2021-Sep-30 at 14:52Read the official Kafka documentation for the version you downloaded, and not some other blog/article that you might have copied the command from
zookeeper is almost never used for CLI commands in current versions
If you run bin\kafka-topics on its own with --help or no options, then it'll print the help messaging that shows all available arguments.

I am editing a file in VS code. VS code gives the following error: Import "selenium" could not be resolved Pylance (reportMissingImports).
This is the code from metachar:
...ANSWER
Answered 2022-Mar-02 at 15:27PyLance looks for the "selenium" python package and cannot find it in the configured python installation. Since you're using VSCode, make sure you've configured the python extension properly. When you open a .py file in VSCode, you should see a python setting in the status bar down below on the left. Select the installation on which you've installed selenium and PyLance will find your import.

parser = optparse.OptionParser()
parser.add_option("-i", "--interface", dest="interface", help="goo")
parser.add_option("-m", "--mac", dest="new_mac", help="yeees")
return parser.parse_args()
def change_mac (interface, new_mac):
print ("changing MAC ADDRESS FOR :{} to {}" (interface, new_mac)
subprocess.call(["ifconfig", interface, "down"]) ## the problem
subprocess.call(["ifconfig", interface, "hw ", " ether ", new_mac])
subprocess.call(["ifconfig", interface, "up"])
get_arguments()
change_mac (options.interface, options.new_mac)
ANSWER
Answered 2022-Mar-02 at 01:17The syntax error is declared at line 17 but actually occurs at the end of line 16. You just need to close the parenthesis of the call of the function print. Also, the way you try to add the variables interface and new_mac in the string is incorrect; you need to use the format function.
Here is the code fixed:
QUESTION
#! /usr/bin/env python
import subprocess
import optparse
def get_arguments():
parser=optparse.OptionParser()
parser.add_option("-i", "--interface", dest="interface", help="interface to change mac adress for")
parser.add_option("-m", "--mac", dest="new_mac", help="change mac address")
return parser.parse_args()
def change_mac(interface, new_mac):
print("changing you mac address")
subprocess.call(["ifconfig ", interface, " down"])
subprocess.call(["ifconfig ", interface, " hw", " ether", new_mac])
subprocess.call(["ifconfig ", interface, " up"])
(options,arguments)=get_arguments()
change_mac(options.interface, options.new_mac)

Answered 2022-Jan-30 at 13:05You have a trailing space in the names of the executables you are passing to subprocess.call, and leading spaces in other arguments. Here's the first line, the other two are similar:

I want to remove the website from further checking process, if my "keyword" on the website got found, so they are not getting still checked multiple times. How can i do this? Iam still a beginner but i linked you my whole Script at the bottom thanks.
If the keyword "google" got found at the currently checking website, i want to remove this website from further checking.
...ANSWER
Answered 2022-Jan-09 at 02:09You can create a collection of whitelists, which will be used to save websites that pass the check, and determine whether they are in the whitelist before starting the thread each time, and skip if they exist.
In the code below, the whitelist collection is temporary.
If you want it to take effect every time you start the program, you can save it to a file, read the file every time you start the program, and write it every time it ends.

Im really hobbist python guys so i dont know hwy is it like this? I think it should be working fine? Can someone explain my why this is not working properly? Im really lost. There is option with arguments like -v is number of votes -s survey url id -t target box that you want to check by getting its id from oid. Its based very much on code that i found on the internet. For me it all looks good? i guess. Is that can be problem with option type strings? That is the exact thing that this code gives me on terminal:
...ANSWER
Answered 2021-Oct-25 at 13:15The error is descriptive: one of the parts you are atempting to concatenate in your log message is a None object, and the "+" operator is not defined for it.
However, concatenating strings with "+" in Python is usually just done by people learning Python coming from other languages. Other ways of interpolating data in strings are far easier to type and read.
From Python 3.6+ the recomended way is interpolating with "f"strings: strings with an f-prefix to the opening quote, can resolve Python expressions placed inside brackets inside it.
So, just replace your erroring line for:
