The >>> prompt evaluates expressions and prionts the value.
The interpreter on the other hand does not automatically print
values you ghave to explicitly tell it to print using the print
statement.

So in your case just add the print command in front of the
function call and all will be well.

> factorial(some number here)

print factorial(n)
