Can you please explain me a part of your code? #1
Description
Hello! I am learning Data Analysis and Python frameworks. I saw your medium article that referred to this GitHub repo. Here I could not understand the code in the 1st cell of part 4 i.e. Variable Selection using Python-Vote based approach. Can you please explain to me the use of defaultdicts and df.select_dtypes functions? And thanks a lot for this wonderful notebook!
