fix: use print() function in both Python 2 and Python 3 (#18395)

Legacy print statements are syntax errors in Python 3 but print() function works as expected in both Python 2 and Python 3.

Old style exceptions are syntax errors in Python 3 but new style exceptions work as expected in both Python 2 and Python 3.
