Show DataFrame as table in iPython Notebook

You’ll need to use the HTML() or display() functions from IPython’s display module: from IPython.display import display, HTML # Assuming that dataframes df1 and df2 are already defined: print “Dataframe 1:” display(df1) print “Dataframe 2:” display(HTML(df2.to_html())) Note that if you just print df1.to_html() you’ll get the raw, unrendered HTML.
