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 with name “x”. After executing this line, this number will be stored into this variable.

How do you create a variable with the numeric value 5 in Python?

They are declared simply by writing a whole number. For example, the statement x = 5 will store the integer number 5 in the variable x. For 64-bit platforms, you can store any whole numbers between -9223372036854775808 and 9223372036854775807 in an integer variable in Python.

How do you type a variable in Python?

Python sets the variable type based on the value that is assigned to it. Unlike more riggers languages, Python will change the variable type if the variable value is set to another value. For example: var = 123 # This will create a number integer assignment var = ‘john’ # the `var` variable is now a string type.

How do you assign a value to a variable?

Assigning values to variables is achieved by the = operator. The = operator has a variable identifier on the left and a value on the right (of any value type). Assigning is done from right to left, so a statement like var sum = 5 + 3; will assign 8 to the variable sum .

How do you create a variable with the numeric value 9?

The = symbol is known as the assignment operator. It is also possible to declare a variable and assign it a value in the same line, so instead of int i and then i = 9 you can write int i = 9 all in one go. If you have more than one variable of the same type you can also declare them together e.g.

How do you create a variable?

To create a variable, you give it a type, a name, and a value.

  3. The value is what the variable points to.
