title: Pandas Regex pattern some cleaning required
body: <p>I have an input text :</p>
  <pre><code>text = '146.204.224.152 - feest6811 [21/Jun/2019:15:45:24 -0700] &quot;POST /incentivize HTTP/1.1&quot; 302 4622\n197.109.77.178 - kertzmann3129 [21/Jun/2019:15:45:25 -0700] &quot;DELETE /virtual/solutions/target/web+services HTTP/2.0&quot; 203 26554\n156.127.178.177 - [21/Jun/2019:15:45:27 -0700] &quot;DELETE /interactive/transparent/niches/revolutionize HTTP/1.1
  
  output Required :['feest6811','kertzmann3129','-']
  
  output getting :[ ' feest6811', ' kertzmann3129',' ']
  
  </code></pre>
  <p>Below is the code used</p>
  <pre><code>user_name = re.findall('(?&lt;=[-])\s[a-zA-Z0-9]*',text)
  </code></pre>
  <p>Second output Required :</p>
  <pre><code>['POST /incentivize HTTP/1.1','DELETE /virtual/solutions/target/web+services HTTP/2.0','DELETE /interactive/transparent/niches/revolutionize HTTP/1.1']
  
  Output getting :
  ['POST /incentivize HTTP/1.','DELETE /virtual/solutions/target/web+services HTTP/2.','DELETE /interactive/transparent/niches/revolutionize HTTP/1.']
  </code></pre>
  <p>Below is the code used for the above second output</p>
  <pre><code>request =  re.findall('[a-zA-Z]*\s/[a-zA-Z].*[.\+]',text)
  </code></pre>
  <p>So as you can see there is small thing that i'm missing in both output 1 and 2</p>
  <p>in output 1 i'm missing '-' signs when we have no data and in second output i'm not able to read the last word after '.'</p>
  <p>Can anyone recommend the necessary changes to the code..</p>
