Title
Body
Say I have a dataframe import pandas as pd import numpy as np foo = pd.DataFrame(np.random.random((10,5))) and I create another dataframe from a subset of my data: bar = foo.iloc[3:5,1:4] does bar hold a copy of those elements from foo ? Is there any way to create a view of that data instead? If so, what would happen if I try to modify data in this view? Does Pandas provide any sort of copy-on-write mechanism?
