Hi I am working on implementing the DataFrame>>dtypes feature which checks the datatypes of columns in a DataFrame, as part of my GSOC project. I have tried to explain my theoretical work done so far on this blog post. Please kindly go through it , as I need advice on what could be the optimal way to implement this feature. Any kind of input and discussions is most welcome.
