CodeRunner: Time limit exceeded

This forum has a limit to the number of forum postings you can make in a given time period - this is currently set at 5 posting(s) in 1 day

Hello,

Well I students are receiving this :

{'centre': (5, 5), 'rayon': 1}↩
False↩
↩
***Time limit exceeded***

when submitting their code in python through coderunner, although the right one is just:

{'centre': (5, 5), 'rayon': 1}↩
False

I could not figure out why.
In my idle everything is working fine.
Regards,
SEA
