Hello

I hereby would like to share the problem I have found regarding python list implementation:-

As per python documentation python list is mutable data object.

That problem I found with the list is that is behaves differently when we use '+=' and '+'  '=' operators separately.
For example-
a=a+1 and a +=1  both behave in same way for all data types except python list

Please find the attached module and execute it on windows python32, See the difference in output.


Kind Regards
