How do you multiply a number by itself in Python?

There are several ways to square a number in Python:

1. The ** (power) operator can raise a value to the power of 2. For example, we code 5 squared as 5 ** 2 .
2. The built-in pow() function can also multiply a value with itself.
3. And, of course, we also get the square when we multiply a value with itself.

What is it called when we get the variable all by itself?

## What is variable give example?

A symbol for a value we don’t know yet. It is usually a letter like x or y. Example: in x + 2 = 6, x is the variable. But in something like y = x + 2 (a linear equation) x can have many values. In general it is much easier to always call it a variable even though in some cases it is a single value.

## How do you declare variables?
