title: Wrong Python version in PyCharm's inspections
body: <p>Project Interpreter in PyCharm's settings for the project
  "Python 3.6 C:\Anaconda\python.exe"</p>
  
  <p>But in my code I get inspections like "Python version 3.5 does not support a 'F' prefix"</p>
  
  <p>There is no Python3.5 on my system anywhere, I tried to resolve this doing the following:</p>
  
  <ul>
  <li>removed the interpreter in pycharm settings, then added it back</li>
  <li>uninstalled all other python versions, deleted their entries from windows registry etc</li>
  <li>updated anaconda / conda etc</li>
  </ul>
  
  <p>nothing is working. And anyway why does PyCharm show that the python version is 3.6 when I select it as the project interpreter, but that it is 3.5 in inspections?</p>
