Yes. If you want something printed, you have to print it.

In your script, you have:


# definition of ExClass not shown
x = ExClass()
x.eyes
x.age
x.height
x.thisMethod()
print x.thisMethod()


This creates an instance of ExClass, calls it "x". Then it retrieves the 
eyes, age and height from x, but does nothing with the results except 
immediately discard them. Then it calls thisMethod, and discards the 
result. Lastly, it calls thisMethod again and prints the result. That is 
the only thing that the script will output.

I recommend you do this instead:


# definition of ExClass not shown
x = ExClass()
print x.eyes, x.age, x.height
print x.thisMethod()
