title: Python class to keep escape sequences
body: <p>I have created simple class to keep escape seqs:</p>
  
  <pre><code>class Color:
      HEAD = '\033[95m'
      OKBL = '\033[94m'
      OKGR = '\033[92m'
      FAIL = '\033[93m'
      WARN = '\033[91m'
      ENDC = '\033[0m'
      BOLD = '\033[1m'
      UNDR = '\033[4m'
  </code></pre>
  
  <p>to use them in console outputs like so:</p>
  
  <pre><code>print(Color.WARN + "Output file will be overwritten!" + Color.ENDC)
  </code></pre>
  
  <p>now get message from linter that class has no <code>__init__</code> method.</p>
  
  <p>Is it OK and I can simply ignore this warning or what would be pythonic way here?</p>
