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
1) Assign: This operator is used to assign the value of the right side of the expression to the left side operand. Syntax: x = y + z. Example: Python3. # Assigning values using . # Assignment Operator. a = 3. b = 5.

Assignment Expressions: The Walrus Operator
In this lesson, you'll learn about the biggest change in Python 3.8: the introduction of assignment expressions.Assignment expression are written with a new notation (:=).This operator is often called the walrus operator as it resembles the eyes and tusks of a walrus on its side.. Assignment expressions allow you to assign and return a value in the same expression.

Python Assignment Operator. The = (equal to) symbol is defined as assignment operator in Python. The value of Python expression on its right is assigned to a single variable on its left. The = symbol as in programming in general (and Python in particular) should not be confused with its usage in Mathematics, where it states that the expressions ...
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.
Variables and Assignment
Variables and Assignment¶. When programming, it is useful to be able to store information in variables. A variable is a string of characters and numbers associated with a piece of information. The assignment operator, denoted by the "=" symbol, is the operator that is used to assign values to variables in Python.The line x=1 takes the known value, 1, and assigns that value to the variable ...
Python Operators
In Python, Assignment operators are used to assigning value to the variable. Assign operator is denoted by = symbol. For example, ... This operator is known as a reference-quality operator because the identity operator compares values according to two variables' memory addresses. Python has 2 identity operators is and is not.
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.
Python Assignment Operators
In Python, an assignment operator is used to assign a value to a variable. The assignment operator is a single equals sign (=). Here is an example of using the assignment operator to assign a value to a variable: x = 5. In this example, the variable x is assigned the value 5. There are also several compound assignment operators in Python, which ...

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?
Augmented Assignment Operators in Python
An assignment operator is an operator that is used to assign some value to a variable. Like normally in Python, we write "a = 5" to assign value 5 to variable 'a'. Augmented assignment operators have a special role to play in Python programming.
Assignment Operators in Python
The primary assignment operator is the simple assignment operator ("="). We then learned that Python supports more complex assignment operators that can be used to calculate values in place. The assignment operators can be used to calculate mathematical, logical, and bitwise operations.
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.

Summary: Python Assignment Operator. Assignment operators are used to assign values to variables. Shorthand assignment is the most commonly used in Python. The table summarizing the assignment operators is provided in the lesson. Assignment Methods. Chain Assignment: A method used to assign multiple variables at one.
Operators and Expressions in Python
In summary, the Python not operator negates the truth value of an object and always returns a Boolean value. ... For a deep dive into how this operator works, check out The Walrus Operator: Python 3.8 Assignment Expressions. Unlike regular assignments, assignment expressions do have a return value, which is why they're expressions. So, the ...
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.
Python Operators
In the example below, we use the + operator to add together two values: Example. print(10 + 5) ... Python Assignment Operators. Assignment operators are used to assign values to variables: Operator Example Same As Try it = x = 5: x = 5:

There is conditional assignment in Python 2.5 and later - the syntax is not very obvious hence it's easy to miss. Here's how you do it: x = true_value if condition else false_value For further reference, check out the Python 2.5 docs.
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 ...

103. Python 3.8 will introduce Assignment Expressions. It is a new symbol: := that allows assignment in (among other things) comprehensions. This new operator is also known as the walrus operator. It will introduce a lot of potential savings w.r.t. computation/memory, as can be seen from the following snippet of the above linked PEP (formatting ...
How does Python's comma operator work during assignment?
32. Python does not have a "comma operator" as in C. Instead, the comma indicates that a tuple should be constructed. The right-hand side of. a, b = a + b, a. is a tuple with th two items a + b and a. On the left-hand side of an assignment, the comma indicates that sequence unpacking should be performed according to the rules you quoted: a will ...

For the future time traveler from Google, here is a new way (available from Python 3.8 onward): b = 1 if a := b: # this section is only reached if b is not 0 or false. # Also, a is set to b print(a, b) This is known as "the walrus operator". More info at the What's New In Python 3.8 page.

Python needs to evaluate condition before evaluating v1 or v2 and it should not evaluate both. So, if you want to use the same value in v1 and condition , you need to use the walrus operator in condition , since that gets evaluated first:
