Vivek-abstract commented 5 years ago

I think the code you're trying to run is for Python 2 as Python 3 has a syntax print() with braces and python 2 doesn't have those braces

ZoranPandovski commented 5 years ago

Yes, that is python 2 syntax. If we change them with print() as a function it will work for both Python 2 & 3

There are a few subtle rules about commas, end=, file=, etc. to watch out for...
