Empty Set in Python

What this snippet does

Using empty curly braces {} creates an empty dictionary, not a set; use set() for empty sets.

Expected output

<class 'dict'>

Why practise typing this

Typing collections code builds muscle memory for the symbols and indentation Python uses most, which prose-based typing tests never cover. DevType measures your words per minute and accuracy on this snippet and tracks the individual characters you mistype, so later lessons can target them.
