One thing that's important to keep in mind as you continue your Python journey is that the Python ecosystem is fragmented. Python 3 was released on December 3rd, 2008, but over a decade later the web is still full of Python 2 dependencies, scripts and tutorials.
In this course, we used Python 3 - just like any good citizen should these days.
One of the most obvious breaking changes between Python 2 and 3 is the syntax for printing text to the console.
print "hello world"
print("hello world")
Update the code from Python 2 to Python 3 syntax.
