title: VSCode is saying variables which use change using += 1 in python should be constants. Is this correct?
body: <p>Here is an extremely simplified version of my code below:</p>
  <pre><code>foo = 0
  bar = 0
  baz = 0
  while True:
      answer = input('Type an input here: ')
      print('And do something with it here.')
      if answer == 'okay':
          foo += 1
      else:
          bar += 1
      baz += 1
      print(foo, bar, baz)
  </code></pre>
  <p>When I save this, VSCode is giving me a warning saying:</p>
  <blockquote>
  <p>Constant name &quot;foo&quot; doesn't conform to UPPER_CASE naming style</p>
  <p>Constant name &quot;foo&quot; doesn't conform to UPPER_CASE naming style</p>
  <p>Constant name &quot;foo&quot; doesn't conform to UPPER_CASE naming style</p>
  </blockquote>
  <p>My question is does the &quot;+= 1&quot; affect whether or not the variable should be a constant? I thought the &quot;+= 1&quot; would cause the variable to not be a constant as the variable changes, but VSCode is telling me otherwise.</p>
