[Question #685331]: NameError Traceback (most recent call last)
New question #685331 on Yade:
https://answers.launchpad.net/yade/+question/685331
Hello,
I am using Ubuntu 18.04, and Yade 2019-08-08.git-775ae74
I have read the wiki and tutorials, struggle with codes as a beginner in yade and asked some questions. Finally, I slightly changed https://.../script-session1.py. I got some errors such as syntax ones and fixed the, but I get the following error repeatedly as follows now:
ehsan@ehsan:~/Desktop$ /home/ehsan/yade/install/bin/yade-2019-08-08.git-775ae74 Q.py

Since I have defined "history()", I don't know what is the problem. Unfortunately couldn't find the answer by googling it.

********************************************************
And also before the error, I get 1 notice as "The constructor with a shareWidget is deprecated, use the regular contructor instead.". I don't know if this affects my code or not.
Could you please let me know if there is any other mistake in this code?
Thank you very much for your help.
