Common questions

Can two variables refer to the same object?

Can two variables refer to the same object?

Yes, two or more references, say from parameters and/or local variables and/or instance variables and/or static variables can all reference the same object.

How do you check whether the two variables are pointing to the same object?

The is keyword is used to test if two variables refer to the same object. The test returns True if the two objects are the same object. The test returns False if they are not the same object, even if the two objects are 100\% equal. Use the == operator to test if two variables are equal.

How can you define multiple variables with same value?

You can assign the same value to multiple variables by using = consecutively. This is useful, for example, when initializing multiple variables to the same value. It is also possible to assign another value into one after assigning the same value.

Can two variables have same address in Python?

Why does python point two variables to a same memory address? [duplicate] Closed last year. turns out that both the addresses are the same. Why is it so unlike C and C++ where every variable has a unique memory address.

What happens when two references point to the same object?

Object reference equality: when two object references point to the same object. Object value equality: when two separate objects happen to have the same values/state.

When two object reference variables contain the address of the same object they are referred to as?

Aliases. Two or more references that refer to the same object. One object and its data can be accessed using different reference variables.

How do you check if two values are the same in Python?

The equality operator (==) is used to compare two values or expressions. It is used to compare numbers, strings, Boolean values, variables, objects, arrays, or functions. The result is TRUE if the expressions are equal and FALSE otherwise.

Can a variable have multiple values?

A variable holds more than one value if you declare it to be of a composite data type. Composite Data Types include structures, arrays, and classes. A variable of a composite data type can hold a combination of elementary data types and other composite types. Structures and classes can hold code as well as data.

How do you declare two variables on the same line in Python?

When assigning multiple variables in a single line, different variable names are provided to the left of the assignment operator separated by a comma. The same goes for their respective values except they should to the right of the assignment operator.

Can two variables have the same memory address?

Yes. They can. In fact more than two independent variables can have the same distribution.

Which operator can be used to determine whether two variables are referring to the same object or not?
