what is the difference between assignment operator and equality operator?

The “=” is an assignment operator is used to assign the value on the right to the variable on the left. The '==' operator checks whether the two given operands are equal or not.

An operator is the 'function' that performs the operation, whereas the operand is the input to that function. In the expression 3 + 4 = 7, the operator is '+' - since it's telling us how to perform the operation - and the operands are 3 and 4 - the inputs upon which the operation is acting.

The comparison operators ( > , == , etc.) are defined to return a signed integer ( int ) result, either 0 (for false) or 1 (for true). Logical operators ( && , || , ! , etc.) and condition-testing statements ( if , while ) assume that zero is false and all other values are true.

Copy constructor vs assignment operator in C++ The main difference between them is that the copy constructor creates a separate memory block for the new object. But the assignment operator does not make new memory space. It uses the reference variable to point to the previous memory block.

The difference between is and as operators are as follows: ... The is operator is of boolean type whereas as operator is not of boolean type. The is operator returns true if the given object is of the same type whereas as operator returns the object when they are compatible with the given type.

So it's cleared now, ,both are not same, = is an Assignment Operator it is used to assign the value of variable or expression, while == is an Equal to Operator and it is a relation operator used for comparison (to compare value of both left and right side operands).

You can use "!= " and "is not" for not equal operation in Python. The python != ( not equal operator ) return True, if the values of the two Python operands given on each side of the operator are not equal, otherwise false .

Arithmetic operators are used to perform mathematical operations. Relational operators are used to perform comparison operations. Logical operators are used to perform basic operation of boolean algebra ('AND', 'OR', and 'NOT'). ... Assignment operator is used to assign value of the second operand to first.

Equality in Python is more complicated than most people realize but at its core you have to implement a __eq__(self, other) method. ... By default, those methods are inherited from the object class that compares two instances by their identity – therefore instances are only equal to themselves.

Two of the many comparison operators used by PHP are '==' (i.e. equal) and '===' (i.e. identical). The difference between the two is that '==' should be used to check if the values of the two operands are equal or not. On the other hand, '===' checks the values as well as the type of operands.

In C++, like other functions, assignement operator function is inherited in derived class. For example, in the following program, base class assignment operator function can be accessed using the derived class object.

Although these operations are probably familiar to you, the Python symbols are different from the mathematical symbols. A common error is to use a single equal sign (=) instead of a double equal sign (==). Remember that = is an assignment operator and == is a comparison operator.

This article explains the basic difference between these two. Both the == Operator and the Equals() method are used to compare two value type data items or reference type data items. ... The == Operator compares the reference identity while the Equals() method compares only contents.

Difference between == and is operator in Python The == operator compares the values of both the operands and checks for value equality. Whereas is operator checks whether both the operands refer to the same object or not. Output of the first if condition is “True” as both list1 and list2 are empty lists.
