title: REGEX \d is not working while reading a glob
body: <p>what I'm trying is to find the highest number of the files that I have in the folder.
  Once decleared the path of the folder, I tried to add the name of the files that I want to read. In that file I want to find any possible number from one to more digits.</p>
  <pre><code>path = &quot;C:/Users/Desktop/Data/noupdated/FEB/batch/csv/&quot;
  files = glob.glob(path + &quot;noupdated_\d+_FEB_españa_info_csv.csv&quot;)
  for file in files:
      print(file)
  </code></pre>
  <p>It should be printing in this case, the following outcome:</p>
  <pre><code>&quot;C:/Users/Desktop/Data/noupdated/FEB/batch/csv/noupdated_0_FEB_españa_info_csv.csv&quot;
  &quot;C:/Users/Desktop/Data/noupdated/FEB/batch/csv/noupdated_1_FEB_españa_info_csv.csv&quot;
  </code></pre>
  <p>But instead, it's not printing anything.</p>
  <p>Thank you! I'm relatively new with the regex syntax.</p>
