''tuple unpacking is not supported in Python3'' error

[ferdicaner]

Hi Dear @MarkPKCollier

I wanted to run the code using python 3.5 on PyCharm, an error occured in file 'Ncross_analysis.py'

''''
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
''''
and it seems like the error is because 'tuple unpacking is not supported in Python3'.

Could you please help me to solve this problem?
How can I change the written code (in the photo), so that it will not be problematic ?

Have a good day
