[Python]Split a Dataframe to a Chunk list

In many cases, you would need to split a huge dataframe to sub chunks so that you can insert or store or persist it to a database.

You may say ,hey, it is a piece of cake, I can simply use numpy.split to make it happen, like this:

import numpy as np
chunk_num = 10
chunks = np.split(my_df,chunk_num)

done? yes, if the df size is 100. but what if the size is 101? np.split is no longer fit the need. Here I created one of my own df split that works for all cases.
