canopy/ipython run script - no output?

I am very new to IPython, but not new to py itself. I am going through some code examples from a book called datadrivensecurity and trying to run one of the code examples. When i create a new file in IPython (using cannopy), then click run, i get the following output in the console window. 

In [9]: %run /Users/myuser/Documents/Notebooks/ch02.py
highvulns     int64
name         object
os           object
dtype: object
In [10]:

When i copy/paste the code into the In[#] console prompt, i get the output expected. What am i doing wrong ?

#
# name ch02.py
#

# create a new data frame

import numpy as np
import pandas as pd

# create a new data frame of hosts & high vuln counts
assets_df = pd.DataFrame( { 
    "name" : ["danube","gander","ganges","mekong","orinoco" ],
    "os" : [ "W2K8","RHEL5","W2K8","RHEL5","RHEL5" ],
    "highvulns" : [ 1,0,2,0,0 ] 
    } )

# take a look at the data frame structure & contents
print(assets_df.dtypes)
assets_df.head()

# show a "slice" just the operating systmes
assets_df.os.head()

# add a new column
assets_df['ip'] = [ "192.168.1.5","10.2.7.5","192.168.1.7",
                     "10.2.7.6", "10.2.7.7" ]

# show only nodes with more than one high vulnerabilty               
assets_df[assets_df.highvulns>1].head()

# divide nodes into network 'zones' based on IP address
assets_df['zones'] = np.where(
    assets_df.ip.str.startswith("192"), "Zone1", "Zone2")

# get one final view
assets_df.head()

highvulns     int64
name         object
os           object
dtype: object

As a convenience, if you type an expression at the prompt, the value of the expression will be printed. But if you just write the same expression in a python file, it will be evaluated, but the value will not be printed. You should print x if you want the value of x to be printed from a file that you are running.
