During discussion of this PEP, the operator became informally known as "the walrus operator".
The construct's formal name is "Assignment Expressions" (as per the PEP title), but they may also be referred to as "Named Expressions" (e.g.
His conclusion: the current proposal would have allowed a modest but clear improvement in quite a few bits of code.
Another use of real code is to observe indirectly how much value programmers place on compactness.
It is used commonly by lawyers, accountants, business people, title companies and others dealing with property.

Without a way to capture sub-expressions inline, this would require refactoring of the original code; with assignment expressions, this merely requires the insertion of a few markers.Removing the need to refactor reduces the likelihood that the code be inadvertently changed as part of debugging (a common cause of Heisenbugs), and is easier to dictate to another programmer.During the development of this PEP many people (supporters and critics both) have had a tendency to focus on toy examples on the one hand, and on overly complex examples on the other.The danger of toy examples is twofold: they are often too abstract to make anyone go "ooh, that's compelling", and they are easily refuted with "I would never write it that way anyway".
