What steps will reproduce the problem? import sys def test(): print "I am testing" sys.stdout.flush() value = input("enter integer") print value What is the expected output? What do you see instead? Expected:
I am testing enter integer ....

Instead: The print statement is not flushed to the screen. What version of the product are you using? On what operating system? JES 4.3 Please provide any additional information below.

Has this been fixed?

input() will not work correctly in JES, because of an interaction between Swing and the Jython interpreter. sys.stdout.flush() is unlikely to work (or rather, it will work, but the Console won't update until the execution ends). That's why we created requestString() instead. These issues are discussed in the book.

Thank you very much. I'm new to the book and teaching the class, so I'm learning as I'm going.
