[python] Invalid syntax when using "print"?

I'm learning Python and can't even write the first example:

print 2 ** 100

this gives SyntaxError: invalid syntax

pointing at the 2.

Why is this? I'm using version 3.1

You need parentheses:

print(2**100)

The syntax is changed in new 3.x releases rather than old 2.x releases: for example in python 2.x you can write: print "Hi new world" but in the new 3.x release you need to use the new syntax and write it like this: print("Hi new world")

check the documentation: http://docs.python.org/3.3/library/functions.html?highlight=print#print

They changed print in Python 3. In 2 it was a statement, now it is a function and requires parenthesis.

Here's the docs from Python 3.0.
