title: ''tuple unpacking is not supported in Python3'' error
body: <p>I wanted to run the code using python 3.5 on PyCharm, an error occured in file 'Ncross_analysis.py'</p>
  
  <pre><code>C:\Users\Eduline\PycharmProjects\python\venv\Scripts\python.exe C:/Users/Eduline/Desktop/GEOMETRİ1/Ncross_analysis.py
  File "", line 15
  def getLine_pixelPoint((x1, y1), (x2, y2)):
  ^
  SyntaxError: invalid syntax
  </code></pre>
  
  <p>and it seems like the error is because 'tuple unpacking is not supported in Python3'</p>
  
  <p>How can I change the written code so that it will not be problematic?</p>
