Unit variables upon their first appearance

Hello there, I have an idea for initializing a variable the first time it’s created; it can especially be helpful with containers, and dicts specifically. Let me demonstrate with some examples: Dic = {} # format fruit:count for fruit in fruits: If fruit in Dic: Dic[fruit]+=1 Else: Dic[fruit]=1 With my proposal, using := to init (similar to how in math parlance, the := is used for defining something for the first time) Dic = {} # format fruit:count For fruit in fruits: Dic[fruit]:= 0 Dic[fruit]+=1 Would be great to hear your feedback. Thanks. Moj

Greetings, This library* seems to be used by many people for some treemap operations. Would it be a good idea to include it in upcoming versions? Leetcode has it by default for the lack of a similar something in Python. I did not check, but it seems other languages cater to structures better. * http://www.grantjenks.com/docs/sortedcontainers/ Thanks.
