[Tutor] trouble using 2to3.py

[Richard D. Moores]

And here's the same try (without the -w switch, to keep it simple),
but this time on my laptop (64-bit Vista SP1). The result is a bit
different:

=====================================
C:\Python31\temp>2to3.py mycalc.py
Traceback (most recent call last):
  File "C:\Python31\temp\2to3.py", line 2, in <module>
    from lib2to3.main import main
  File "C:\Python31\temp\lib2to3\main.py", line 121
    print("At least one file or directory argument required.", file=sys.stderr)
                                                                   ^
SyntaxError: invalid syntax

C:\Python31\temp>python
