Python: Duck Typing - What it really means!

Duck-typing is one of the most misunderstood concepts in dynamic OO design. I found many explanations for duck-typing, not to the point. So, in this video, I have attempted my own take on explaining duck-typing for those of you who still find it confusing.

This video explains problem-solving without using duck-typing (the traditional approach) for the first 20 minutes and then introduces how the problem can be solved using a duck-typing approach with the advantages.
