Syntax error for simple script

[pstein]

Sorry for this newbie question:

I installed Python v3.6.1 on win 7. Afterwards I tried to execute the following simple python script
from webpage www.pythonforbeginners.com/code-snippets-source-code/date-and-time-script/:

from datetime import datetime
now = datetime.now()
mm = str(now.month)
dd = str(now.day)
yyyy = str(now.year)
hour = str(now.hour)
mi = str(now.minute)
ss = str(now.second)
print mm + "/" + dd + "/" + yyyy + " " + hour + ":" + mi + ":" + ss

When executing

D:\tools\python\python.exe dateParser.py

it yields a syntax error:

 File "dateParser.py", line 17
   print mm + "/" + dd + "/" + yyyy + " " + hour + ":" + mi + ":" + ss
          ^
SyntaxError: Missing parentheses in call to 'print'

Whats wrong?

Thank you
Peter
