title: Exclude .env directory from flake8 tests?
body: <h1>Problem</h1>
  
  <p>I'm getting thousands of flake8 errors stemming from my local .env. An example of some of the error messages:</p>
  
  <pre><code>./env/lib/python3.7/site-packages/pip/_vendor/pyparsing.py:3848:80: E501 line too long (85 &gt; 79 characters)

  <p>My directory looks like this:</p>
  
  <p><a href="https://i.stack.imgur.com/uDov1.png" rel="noreferrer"><img src="https://i.stack.imgur.com/uDov1.png" alt="enter image description here"></a></p>
  
  <p>My flake8 file looks like this:</p>
  
  <pre><code>[flake8]
  exclude =
      migrations,
      __pycache__,
      manage.py,
      settings.py,
  </code></pre>
  
  <h1>Question</h1>
  
  <p>How can I add my env file contents to the exclude list in flake8?</p>
  
  <h1>What I've tried</h1>
  
  <p>I've tried adding:</p>
  
  <pre><code>  env,
  ./env,
  </code></pre>
  
  <p>I've tried taking off commas and adding:</p>
  
  <pre><code>[flake8]
  exclude =
      migrations
      __pycache__
      manage.py
      settings.py
      env
      .env
      ./env
      env/
      .env/
  </code></pre>
