[Tutor] re-directing print statements in exec

[Toby Donaldson]

Hi all,
 
I am wondering if there is any easy way to make a print statement in an
exec statement get sent to a string instead of the console. For
instance,
 
>>> prog = """
r = 5
print 3.14 * r ** 2
"""
>>> exec prog
78.5
 
The result gets printed to the console. But instead, I'd like it to be
in a string.
 
Any suggestions?
 
Toby
