It is possible to show list/dictionary generator progress in python?

Question

I build very big dictionary (2^20 elements) in python using dictionary generator expression (i'm using IDLE for this). The process is very long because of every element needs hard computing. It is possible to get known progress of this operation?

I understand that it is easy to do if don't use generator expressions, but nevertheless this question is interesting I think.

Answer 1

If you use yield to write a generator function instead of just using a generator statement, you could put logging or some other sort of feedback before every yield statement.
