if not self._isExecutable(cmd[0]):
            em = f"Error: Did not find executable '", cmd[0], "'."
            em += "       Make sure it is on the PATH variable of your  #operating system."
            raise RuntimeError(em)

The assignment of the string to em is a tuple, and thus not able to add the second line ("Make sure it is on the PATH variable of your operating system.")

solution would be:

if not self._isExecutable(cmd[0]):
            em = f"Error: Did not find executable '{ cmd[0]}'."
            em += "       Make sure it is on the PATH variable of your  #operating system."
            raise RuntimeError(em)
