The Python return Statement: Usage and Best Practices
The Python return statement is a special statement that you can use inside a function or method to send the function's result back to the caller. A return statement consists of the return keyword followed by an optional return value.The return value of a Python function can be any Python object, and you can use them to perform further computation in your programs.
Here, variable represents a generic Python variable, while expression represents any Python object that you can provide as a concrete value—also known as a literal—or an expression that evaluates to a value. To execute an assignment statement like the above, Python runs the following steps: Evaluate the right-hand expression to produce a concrete value or object.
python
The syntax . def x(): print(20) is basically the same as x = lambda: print(20) (there are some differences under the hood, but for most pratical purposes, the results the same).. The syntax. def y(t): return t**2 is basically the same as y= lambda t: t**2.When you define a function, you're creating a variable that has the function as its value.
The Python Return Statement : Usage and Best Practices
7. In this example, the add_numbers function takes two arguments, adds them together, and returns the sum. The returned value is then assigned to the variable result, and when we print the value of the result, it displays 7 on the console.
The Walrus Operator: Python 3.8 Assignment Expressions
Each new version of Python adds new features to the language. For Python 3.8, the biggest change is the addition of assignment expressions.Specifically, the := operator gives you a new syntax for assigning variables in the middle of expressions. This operator is colloquially known as the walrus operator.. This tutorial is an in-depth introduction to the walrus operator.
Python Return Statements Explained: What They Are and Why You Use Them
All functions return a value when called. If a return statement is followed by an expression list, that expression list is evaluated and the value is returned:
The return Statement: Returning Values from Functions in Python
The return statement is a key element of functions in Python. It is used to explicitly return a value or object from a function back to the caller. Understanding how to properly return values from functions is fundamental to writing reusable, modular code in Python.
Python return statement
A return statement is used to end the execution of the function call and "returns" the result (value of the expression following the return keyword) to the caller. The statements after the return statements are not executed. If the return statement is without any expression, then the special value None is returned.
Python Return Multiple Values
You can return multiple values from a function in Python. To do so, return a data structure that contains multiple values, like a list containing the number of miles to run each week. def miles_to_run(minimum_miles): week_1 = minimum_miles + 2 week_2 = minimum_miles +
Python: Return Multiple Values from a Function • datagy
In this tutorial, you'll learn how to use Python to return multiple values from your functions.This is a task that is often quite difficult in some other languages, but very easy to do in Python. You'll learn how to use tuples, implicitly or explicitly, lists, and dictionaries to return multiple values from a function.
Python Functions Exercise with Solution [10 Programs]
Python function is a code block or group of statements that perform a particular task. We use reuse functions whenever required. This Python functions exercise aims to help Python developers to learn and practice how to define functions.Also, you will practice how to create and use the nested functions and the function arguments effectively.
PEP 572
This shows that what looks like an assignment operator in an f-string is not always an assignment operator. The f-string parser uses : to indicate formatting options. To preserve backwards compatibility, assignment operator usage inside of f-strings must be parenthesized.
Assignment Operators in Python
The Python Operators are used to perform operations on values and variables. These are the special symbols that carry out arithmetic, logical, and bitwise computations. The value the operator operates on is known as the Operand.

In Python, is it possible to make multiple assignments in the following manner (or, rather, is there a shorthand): import random def random_int(): return random.randint(1, 100) a, b = # for ...
Different Forms of Assignment Statements in Python
We use Python assignment statements to assign objects to names. The target of an assignment statement is written on the left side of the equal sign (=), and the object on the right can be an arbitrary expression that computes an object.
Returning a function from a function
A function is an instance of the Object type. You can store the function in a variable. You can pass the function as a parameter to another function.
typing
The function surface_area_of_cube takes an argument expected to be an instance of float, as indicated by the type hint edge_length: float.The function is expected to return an instance of str, as indicated by the -> str hint.. While type hints can be simple classes like float or str, they can also be more complex.The typing module provides a vocabulary of more advanced type hints.
In python, return value only when the function is used in an assignment
There is no advantage to controlling return values in Python, because object lifetime is controlled with reference counting, not with assignments to names.

@jonrsharpe Not that I am advocating for this in any way, but there is one scenario that the assignment would have an effect: if you wish to both return a value and set a global variable to that value.
