title: How to open multiple files one-by-one and print the contents in Python
body: <p>I'm working on a function that reads multiple files (from their filenames in a single file) one-by-one. I set up the means of getting the amount of filenames in the file, but I'm not sure what I should use in the loop sequence. Here is where I am at now:</p>
  
  <pre><code>with open('userdata/addedfiles', 'r') as read_files:
          number_of_files = sum(1 for _ in read_files)
  
      print(number_of_files, "files added")
      print("File contents: \n")
  
      # get individual filenames in file and
      # read them one by one
  
      for x in range(number_of_files):
          # hmm...
  </code></pre>
  
  <p>Any suggestions on what to use here? Thanks.</p>
