I am not sure we support running Qiling from an interactive Python interpreter.. I'll leave it to the others comment.
Mean while, I would prefer a code change to be a little bit explanatory about what was the change and why (putting a vague exception name int he comments without a proper context doesn't help much...).

What about surrounding the problematic code with the appropriate try / catch and add comments it's for woroking around IDLE exceptions..?

i never use IDLE, not too sure will it even break the stdio. i guess @kabeor or @wtdcode know more.
