title: Find a file recursively using python
body: <p>I have the below files located at some location in RHEL machine. 
  temp_file2.txt
  temp_file3.txt</p>
  
  <p>Looking for a python script to find above files recursively in all directories(I used a wild card, but it didn't work), and print a message if the file exists or not.</p>
  
  <p>The below code snippet returns Nothing</p>
  
  <pre><code>import glob
  
  for filename in glob.iglob('*/*.txt', recursive=True):
      print(filename)
  </code></pre>
  
  <p>It returns the file name if it exists only in the current working directory</p>
  
  <pre><code>import glob
  
  for filename in glob.iglob('.txt', recursive=True):
      print(filename)
  </code></pre>
