A place to play around with the OpenCV-Python Tutorials.
I use Python 2.x - seems to work fine so far. (As well as Anaconda IDE for Python 2.x).
Even though the OpenCV 2.x version is very mature and well documented, the OpenCV-Python Tutorials are written base on OpenCV 3.x version.
When I first started the tutorial I used OpenCV 2.x - but when I progressed I realized the need to try out OpenCV 3.x (So what the tutorial produces mataches to what I produce locally on my machine).
To prevent having a mix of OpenCV 2.x and 3.x codes, I shall stick to OpenCV 3.x for the duration of the OpenCV-Python Tutorials as suggested by the Authors.
This Stackoverflow Forum will provide some top tips and hints on getting OpenCV (2.x and/or 3/x) working with Python 2.x Anaconda.
