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.

The not-equal operator, != , is the opposite, evaluating to true if the values are different. Typically, you use == and != with primitives such as int and boolean, not with objects like String and Color.

equals() checks if two objects are the same or not and returns a boolean. compareTo() (from interface Comparable) returns an integer. It checks which of the two objects is "less than", "equal to" or "greater than" the other. ... Note that equals() doesn't define the ordering between objects, which compareTo() does.

Conclusion. 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).

What is the difference between = (Assignment) and == (Equal to) operators. 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. If so, it returns true.

Comparing objects is easy, use === or Object.is(). This function returns true if they have the same reference and false if they do not.

Answer: Use the === Operator You can use the strict equality operator ( === ) to check whether a string is empty or not.

In one word, main difference between "==" and "===" operator is that formerly compares variable by making type correction e.g. if you compare a number with a string with numeric literal, == allows that, but === doesn't allow that, because it not only checks the value but also type of two variable, if two variables are ...

['The is operator is used to check if the run-time type of an object is compatible with the given type or not whereas as operator is used to perform conversion between compatible reference types or Nullable types.', 'The is operator is of boolean type whereas as operator is not of boolean type.']

Difference between == and equals in Java. Main difference between == and equals in Java is that "==" is used to compare primitives while equals() method is recommended to check equality of objects.

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.

Answer: Use the equality operator ( == ) In JavaScript if a variable has been declared, but has not been assigned a value, is automatically assigned the value undefined . Therefore, if you try to display the value of such variable, the word "undefined" will be displayed.

In Python, If Statement is used for decision making. It will run the body of code only when IF statement is true. When you want to justify one condition while the other condition is not true, then you use "if statement". Code Line 8: The variable st is set to "x is less than y."

In simple words, == checks if both objects point to the same memory location whereas . equals() evaluates to the comparison of values in the objects. Explanation: Here we are creating two objects namely s1 and s2. Both s1 and s2 refers to different objects.

Python assigns boolean values to values of other types. For numerical types like integers and floating-points, zero values are false and non-zero values are true. For strings, empty strings are false and non-empty strings are true.
