To create a new variable or to update the value of an existing one in Python, you'll use an assignment statement. This statement has the following three components: A left operand, which must be a variable. The assignment operator ( =) A right operand, which can be a concrete value, an object, or an expression.
Assignment Operators in Python
The Walrus Operator in Python is a new assignment operator which is introduced in Python version 3.8 and higher. This operator is used to assign a value to a variable within an expression. Syntax: a := expression. Example: In this code, we have a Python list of integers. We have used Python Walrus assignment operator within the Python while loop.

Python Assignment Operators. Assignment operators are used to assign values to variables: Operator. Example. Same As. Try it. =. x = 5. x = 5.
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.

Since Python 3.8, code can use the so-called "walrus" operator (:=), documented in PEP 572, for assignment expressions.This seems like a really substantial new feature, since it allows this form of assignment within comprehensions and lambdas.. What exactly are the syntax, semantics, and grammar specifications of assignment expressions?
PEP 572
Unparenthesized assignment expressions are prohibited for the value of a keyword argument in a call. Example: foo(x = y := f(x)) # INVALID foo(x=(y := f(x))) # Valid, though probably confusing. This rule is included to disallow excessively confusing code, and because parsing keyword arguments is complex enough already.
6. Expressions
No builtin Python types implement this operator. Added in version 3.5. The / (division) and // (floor division) operators yield the quotient of their arguments. The numeric arguments are first converted to a common type. Division of integers yields a float, while floor division of integers results in an integer; the result is that of ...
Python Assignment Operators
Assignment operators in Python. The above code is useful when we want to update the same number. We can also use two different numbers and use the assignment operators to apply them on two different values. num_one = 6. num_two = 3. print(num_one) num_one += num_two. print(num_one) num_one -= num_two.
Python Operators (With Examples)
Assignment operators are used to assign values to variables. For example, # assign 5 to x x = 5. Here, = is an assignment operator that assigns 5 to x. Here's a list of different assignment operators available in Python.
Different Assignment operators in Python
The Simple assignment operator in Python is denoted by = and is used to assign values from the right side of the operator to the value on the left side. Input: a = b + c. Add and equal operator. This operator adds the value on the right side to the value on the left side and stores the result in the operand on the left side. Input: a = 5. a += 10.
Assignment Operator in Python
The simple assignment operator is the most commonly used operator in Python. It is used to assign a value to a variable. The syntax for the simple assignment operator is: variable = value. Here, the value on the right-hand side of the equals sign is assigned to the variable on the left-hand side. For example.
Python Operators: Arithmetic, Assignment, Comparison, Logical, Identity, Membership, Bitwise. Operators are special symbols that perform some operation on operands and returns the result. For example, 5 + 6 is an expression where + is an operator that performs arithmetic add operation on numeric left operand 5 and the right side operand 6 and ...

In-place Operators¶. Many operations have an "in-place" version. Listed below are functions providing a more primitive access to in-place operators than the usual syntax does; for example, the statement x += y is equivalent to x = operator.iadd(x, y).Another way to put it is to say that z = operator.iadd(x, y) is equivalent to the compound statement z = x; z += y.
Assignment Operators in Programming
Assignment operators are used in programming to assign values to variables. We use an assignment operator to store and update data within a program. They enable programmers to store data in variables and manipulate that data. The most common assignment operator is the equals sign (=), which assigns the value on the right side of the operator to ...

Python Identity Operators. Identity operators are used to compare the objects, not if they are equal, but if they are actually the same object, with the same memory location: Operator. Description. Example. Try it. is. Returns True if both variables are the same object. x is y.
3. An Informal Introduction to Python
This example introduces several new features. The first line contains a multiple assignment: the variables a and b simultaneously get the new values 0 and 1. On the last line this is used again, demonstrating that the expressions on the right-hand side are all evaluated first before any of the assignments take place.

1. Most sources online call = (and +=, -=, etc...) an assignment operator (for python). This makes sense in most languages, however, not in python. An operator takes one or more operands, returns a value, and forms an expression. However, in python, assignment is not an expression, and assignment does not yield a value.
Python Operators
Arithmetic Operators in Python. Python Arithmetic operators are used to perform basic mathematical operations like addition, subtraction, multiplication, and division.. In Python 3.x the result of division is a floating-point while in Python 2.x division of 2 integers was an integer.
how does python assignment(=) operator work
In Python, evaluation is in reverse order. Therefore this: The assignment node.next = node = ListNode(10) is the equivalent of tmp = ListNode(10); node.next = tmp; node = tmp, with the tmp variable hidden. The answer as written suggests that node isn't changed by the assignment, which isn't correct. @Craig Thanks.
Is it possible to overload Python assignment?
It is almost the last operator being resolved just (| & ^) and logical are lower. It is rarely used (__lrshift__ is less, but it can be taken to account). Within using of PyPi assign package only forward assignment can be controlled, so actual 'strength' of the operator is lower. PyPi assign package example:
Is it possible to override the assignment ('=') operator in Python?
I think this would violate Python's object model or variable/naming scheme. A name does not represent one object only, but just points to an object under the hood. Using the assignment operator just changes the object a name points to. -
