sys.stdin in Wing IDE problem

Hi.Trying to test simple python-program using stdin object.

import sys

w = []
for s in sys.stdin:


To stop inputing I send EOF with right-button mouse click. But program terminates and nothing print out.This situation is in Wing IDE 101 under MacOS and Windows.

So, I can't run and test any program that uses stdin.

How can I solve this problem?

That program doesn't work outside of wing either.

If you are writing test code, try putting your inputs into a file and reading from the file.  Then you can use UnitTest instead of typing the same inputs over and over

But the problem with the above program is not wing.

It's strange, but this program works good.

Here is a screenshot.

In bash I can stop inputting sending Ctrl+D.And this is from Wing 

And here is video from PyCharm

The program does work for me outside of Wing and I see that it's not working in Wing in either Python Shell or when debugged. The reason for this is apparently that sending EOF doesn't seem to be working. We'll look into what is causing that.

A work-around is to go into the Options menu in the Debug I/O tool and select Configure External Console. Then check on Use External Console. You'll get a separate console window when you debug and pressing Ctrl-D there to send EOF does work and it prints the output and exits.

Thanks for reporting this and sorry for the slow response. We just moved the Q&A forum to another provider and I think we didn't get notice of your question because it hasn't been fully configured yet.

This will be fixed in the Debug I/O, Python Shell, and Debug Probe tools (so the Send EOF item in right-click menu works) in Wing 6.1.6+ and 7rc1+.
