title: Errors with Glob while outputting file names
body: <p>I am combining two questions here because they are related to each other. </p>
  
  <p>Question 1: I am trying to use glob to open all the files in a folder but it is giving me "Syntax Error". I am using Python 3.xx. Has the syntax changed for Python 3.xx?</p>
  
  <p>Error Message:</p>
  
  <pre><code>File "multiple_files.py", line 29
  files = glob.glob(/src/xyz/rte/folder/)
  
  SyntaxError: invalid syntax
  </code></pre>
  
  <p>Code:</p>
  
  <pre><code>import csv
  import os
  import glob
  from pandas import DataFrame, read_csv
  
      #extracting
  files = glob.glob(/src/xyz/rte/folder/)
  for fle in files:
      with open (fle) as f:
          print("output" + fle)                   
  f_read.close()
  </code></pre>
  
  <p>Question 2: I want to read input files, append "output" to the names and print out the names of the files. How can I do that?</p>
  
  <p>Example: Input file name would be - xyz.csv and the code should print output_xyz.csv .</p>
  
  <p>Your help is appreciated. </p>
