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 Assignment Operators
Python Assignment Operators. Assignment operators are used to assign values to variables: Operator. Example. Same As. Try it. =. x = 5. x = 5.
Different Forms of Assignment Statements in Python
Multiple- target assignment: x = y = 75. print(x, y) In this form, Python assigns a reference to the same object (the object which is rightmost) to all the target on the left. OUTPUT. 75 75. 7. Augmented assignment : The augmented assignment is a shorthand assignment that combines an expression and an assignment.

In any context where arbitrary Python expressions can be used, a named expression can appear. This is of the form name := expr where expr is any valid Python expression, and name is an identifier. The value of such a named expression is the same as the incorporated expression, with the additional side-effect that the target is assigned that value
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 ...
Assignment Operators in Python
Assignment Operator. Assignment Operators are used to assign values to variables. This operator is used to assign the value of the right side of the expression to the left side operand. Python. # Assigning values using # Assignment Operator a = 3 b = 5 c = a + b # Output print(c) Output. 8.
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.
Variables & Assignment
In this subsection, we will demonstrate how to define variables in Python. In Python, the = symbol represents the "assignment" operator. The variable goes to the left of = , and the object that is being assigned to the variable goes to the right:
Python
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 ...
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 ...
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.
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.
What is Assignment Operator in Python?
So, assignment operators are used to assigning values to the operands on the left-hand side. Assignment operators assign the right-hand side values to the operand that is present on the left-hand side. The assignment operator in Python is used as the "=" symbol. Let's see a very basic example of the assignment operator.
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.
7. Simple statements
An assignment statement evaluates the expression list (remember that this can be a single expression or a comma-separated list, the latter yielding a tuple) and assigns the single resulting object to each of the target lists, from left to right. Assignment is defined recursively depending on the form of the target (list).
Python Operators (With Examples)
Python Assignment Operators. 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. Operator Name Example = Assignment Operator:
Operators and Expressions in Python
The assignment operator is one of the most frequently used operators in Python. The operator consists of a single equal sign ( = ), and it operates on two operands. The left-hand operand is typically a variable , while the right-hand operand is an expression.
Python Operators
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.

1. In python and other languages like C, "=" is a assignment operator and is used to assign a value to a variable. Example: a=2 # the value of a is 2. whereas "==" is Comparison operator and is used to check whether 2 expressions give the same value .Equality check returns true if it succeeds and else return false. Example: a=2 b=3 c=2.
