• Methods to remove Time Limit exceeded error from my code?

  This is the question, for which I have written the solution.

  It shows Time Limit Exceeded(TLE) error.

  Pls suggest how do I optimise it further.

• Python Custom Config Files for Modules

  I have below Directory Structure:
  |-- masterFile.py
  |-- firstFolder
  |-- |-- first.py
  |-- |-- configFile
  |-- SecondFolder
  |-- |-- second.py
  |-- |-- configFile
  

  I have many folders like (firstFolder, secondFolder...) and all their python files have same type of code only difference is on processing the variables from config file. I have put all the common code in masterFile.py file and the variable processing has been kept in first.py,m second.py files as a function.

  What I want to do is: I will run the masterFile.py file and depending on some input/signal I will call the fucntion from first.py, second.py .. file and I want them to be run with their own config file variables.

  I am using below code format:
  

  In first.py, second.py

  import os
  import configparser
  config = configparser.ConfigParser()
  config.read(os.path.join(os.path.dirname(__file__),'config'))
  var1 = config['xyz']['abc']
  var2 = config['jkl']['mno']
  
  def doSomeMagic(INPUT_VAR):
      someProcessing_on var1, var2 & INPUT_VAR
  

  Importing the modules in masterFile.py

  from firstFolder import first
  from secondFolder import second
  
  
  initialization_of INPUT_VAR
  
  if SIGNAl == 1:
     first.doSomeMagic(INPUT_VAR)
  

  Depending on some input/signal, I will call doSomeMagic function from first.py, second.py ... files. I want these function to use their config file but Config files are not accessible when I am following this format/structure. < br>

  Any help on how to Achieve this and any advice to change these formats/stucture to make more Pythonic way.

  I have some folder with name starting with a digit like: 7Yes

  from 7Yes import 7yes

• Adopting code from Oddsportal URL to current & Next Page

  I have a code that scrapes

  https://www.oddsportal.com/soccer/england/premier-league/

  odds and event data.

  I want to adopt the same to get all data for "today" which is reflected at

  https://www.oddsportal.com/matches/soccer/

  and 'tomorrow' is

  https://www.oddsportal.com/matches/soccer/20210309/

  which is essentially url/today+1

  My current code that works is:

  browser = webdriver.Chrome()
  browser.get("https://www.oddsportal.com/soccer/england/premier-league/")
  
  df = pd.read_html(browser.page_source, header=0)[0]
  
  dateList = []
  gameList = []
  home_odds = []
  draw_odds = []
  away_odds = []
  
  for row in df.itertuples():
      if not isinstance(row[1], str):
          continue
      elif ':' not in row[1]:
          date = row[1].split('-')[0]
          continue
      time = row[1]
      dateList.append(date)
      gameList.append(row[2])
      home_odds.append(row[4])
      draw_odds.append(row[5])
      away_odds.append(row[6])
  
  result = pd.DataFrame({'date': dateList,
                         'game': gameList,
                         'Home': home_odds,
                         'Draw': draw_odds,
                         'Away': away_odds})
  

  Because the datelist[] is different to the links e.g. Algeria»Ligue 1 I am getting an error

  NameError: name 'date' is not defined
  

  How can I adopt the same to

  https://www.oddsportal.com/matches/soccer/

  and for tomorrow ?

• Getting "Failed to load resource: net::ERR_HTTP2_PROTOCOL_ERROR" while running Python Selenium test scripts

  I am running the test scripts with chrome browser using python selenium test scripts.

              chromedriver = '.\\chromedriver.exe'
  
              options = webdriver.ChromeOptions()
              options.add_argument('--headless')

              options.add_argument('window-size=1920x1080')
  

  Cannot share the whole code but I have used sleep, implicit and explicit waits to slow down the webpage loads but still I am getting different failures in each time. The least errors I have seen is 6 out of 120 test cases and there is only 1 of them is a real failure. I thought about AJAX failure so I have added the waits mentioned above but still cannot trust the test scripts.

  I am taking the screenshots of the failures and my only option would be to run the failed test cases one more time to see if they would pass.

  Any suggestions are welcomed. Thank you for your time.
• Selenium ChromeDriver Action and SendKeys don´t press the button

  I have a problem with my SeleniumDriver and it drives me crazy. I almost tried every solution on stackoverflow..

  My simple goal is to send a key to the browser, but not to an element. My key is "mediaTrackNext" and can be found at

  Windows.Forms.Keys.MediaNextTrack
  

  I tried almost any solution:

  Dim actions As Actions = New Actions(TestBot)
  actions.SendKeys(Windows.Forms.Keys.MediaNextTrack).Perform()
  

  or

  TestBot.FindElement(By.XPath("/html/body")).SendKeys(Windows.Forms.Keys.MediaNextTrack)
  

  or

  Dim actions As Actions = New Actions(TestBot)
  actions.SendKeys(TestBot.FindElement(By.XPath("//body")), Keys.F12).Perform()
  

  I can´t even send keys like F12 to open the developers console, nothing happens.. F5 doesn´t work as well. And yes, I tried a few Tags and xpaths, but no tag seem to work.

  Is there another way? I am so stuck right now..

  Thank you. Best regards, xored
• Escping quotes in PHP regex

  How can I find only the telephone number (1234827382) in the following string ($x)?

  IMPORTANT: I used htmlspecialchars() function on $x (text). Without useing this function the regex works. I need to find a regex solution when I use htmlspecialchars() before regex.

   font-size: 14px; color: #333;" >asd:</td> <td width="150" align="left" valign="top"
      bgcolor="#f5f5f5" style="padding: 6px; border: 1px solid
      #eaeaea;font-family: Arial, Helvetica, sans-serif; font-size: 14px; color:
      #333;" >Tel:</td> <td align="left" valign="top" style="padding: 6px;
      border: 1px solid #eaeaea;font-family: Arial, Helvetica, sans-serif;
      font-size: 14px; color: #333;" ><a href="tel:1234827382">1234827382</a></td> </tr>
  <tr> <td width="150" align="left"
  

  I have tried:

  $p = '/href="tel:12.{20}/';
  preg_match_all($p, $x, $matchestel);
  print_r($matchestel);
  

  If I try escape with \ then it also dont work:

  $p = '/href=\"tel:12.{20}/';
  

  If the text doesnt contain quote: <a href=tel:1234827382" (instead of this: <a href="tel:1234827382" ) then it finds, and after that I could remove the href" from the beginning. I know it is not the best solution. I think the problem is that I need to escape the " from pattern.
• Several commands in one line for cronjob in hiera (Puppet) yaml

  I have hieradata yaml file with a lot of options and some cronjobs I want to add one more cronjob that contain several bash commands in it with quotes:

  hbase_test:
        cron: '*/5 * * * *'
        user: 'root'
        command: '(date && echo "describe \'my_table\'; exit" | hbase shell) >> hbase_test.log 2>&1;'
        flock: true
  

  But this doesn't work - puppet fails to load such yaml. I also tried next way:

  command: "(date && echo \"describe 'my_table'; exit\" | hbase shell) >> hbase_test.log 2>&1;"
  

  Puppet is ok, hbase starts successfully, but fails:

  describe my_table; exit
  NameError: undefined local variable or method `my_table' for #<Object:0xf9f041c>
  

  The right command must be:

  describe 'my_table'; exit
  

  I lost quotes! And I don't know how to escape them in right way. I also tried

  command:>
    (date && echo "describe 'my_table'; exit" | hbase shell) >> hbase_test.log 2>&1;
  

  But cron doesn't start.
• awk inside qsub: issues with awk $

  Consider this working awk one-liner: awk '$1 ~ /hello/' a.txt. When I attempt to submit it to qsub, $1 is incorrectly recognized as a shell variable and replaced with empty space:

  awk ' ~ /hello/' a.txt.

  I tried suggestions in Using awk with qsub and issues with quotations, including \$1 and

  qsub -- awk '$1 ~ /hello/' a.txt.

  Neither works.

  I can certainly put awk in a script and call qsub that way, i.e., qsub awkscript.sh. However, if there's a way to use qsub+awk from the command line, I'd like to learn how.
