Thanks to Python 3.8 new characteristic It will likely be doable to complete such a thing from this Variation, Whilst not making use of = but Ada-like assignment operator :=. Illustration from the docs:
We briefly touched on variables ahead of. It is necessary to assign values to your variable before you decide to utilize it, or you can obtain an mistake:
Contrary to expressions, assignment statements don’t Possess a return benefit due to the fact their intent is to help make the association amongst the variable and its benefit. That’s why the Python interpreter doesn’t challenge any output in the above examples.
Up to this point, you’ve uncovered a good deal about the Python assignment operator and how to use it for composing differing kinds of assignment statements. In the following sections, you’ll dive into an incredible element of assignment statements in Python. You’ll understand augmented assignments.
Be a part of us and obtain use of thousands of tutorials, palms-on video clip classes, along with a Neighborhood of pro Pythonistas:
Copied! Once you utilize a assets-based attribute given that the remaining operand in an assignment assertion, Python immediately calls the house’s setter process, operating any computation from it.

I am a knowledge analyst and software package developer. I take pleasure in educating and need to help students in reaching their academic objectives.
As being a language, Python is basically applied as dynamically typed, object oriented and procedural, but it's multi-paradigm in addition to supports purposeful programming and powerful typing. It is also reflective, which implies Python courses have the ability to modify them selves throughout execution.
Every single tutorial at Authentic Python is created by a staff of builders so that it fulfills our high-quality standards. The staff associates who labored on this tutorial are:
Copied! In this instance, instead of making use of parallel assignment to swap values involving variables, you use a new variable to quickly shop the value of previous_value to avoid getting rid of its reference.
One more exciting example of making use of an augmented assignment is when you have to implement a countdown when loop to reverse python assignment taking service an iterable. In this instance, You should use the -= operator:
