.Buildings.Utilities.IO.Python_3_8.Functions.exchange

Information

This function is a wrapper for Buildings.Utilities.IO.Python_3_8.Functions.BaseClasses.exchange. It adds the directory modelica://Buildings/Resources/Python-Sources to the environment variable PYTHONPATH prior to calling the function that exchanges data with Python. After the function call, the PYTHONPATH is set back to what it used to be when entering this function. See Buildings.Utilities.IO.Python_3_8.UsersGuide for instructions, and Buildings.Utilities.IO.Python_3_8.Functions.Examples for examples.
