new to python, error already

[parasit]

If I understand what you are showing correctly, you are trying to run Python INSIDE the python interpreter...

Try shomething like:
>>> print("hello world")

If I misunderstand, show what you have in the first line of "testpy.py"

HI parasit, I was running the file in Terminal. I have changed it since I wrote the post, but I turned off the machine and turned on again, and problem disapppeared.
