Problem Statement
In Python 3.9+, which merges two dicts into a new one?
Explanation
The vertical bar operator returns a new dict with keys from both, where right side wins on conflicts. The update method mutates in place instead.
This operator makes merges expressive and avoids accidental mutation of the original mapping.

a={'x':1}
