I am trying to run my first program/script (pardon my bad terminology, I am a newbie), and just doesn't work. I am using Ubuntu, and IDLE. and I have written:

print "Hello, world!"

I saved the file as hello.py. Tried to click Run - Run Module, but then it says "Invalid syntax".
Also tried to write "python hello.py" in the python shell, but then I got:
SyntaxError: invalid syntax (<pyshell#13>, line 1)

Anyone knows how to get my program to work? Would really appreciate the help.

print("Hello World") You are probably using Python 3.

alternatively, you could just press F5 while inside IDLE

Thank you very much! It worked when I added ().
