How to Use Exponents in Python

The ** Operator

The simplest way to calculate exponents in Python is using the ** operator. For example, 2 ** 3 will return 8, which represents 2 raised to the power of 3.

Using the pow() Function

Python’s built-in pow() function can also calculate exponents. It takes two arguments, the base and the exponent, like this: pow(2, 3) which also returns 8.

Handling Large Exponents

For larger numbers, Python can handle very high exponents due to its ability to work with arbitrary-precision integers. Just use the ** operator or pow() and Python will handle the large values efficiently.

Negative Exponents

Python supports negative exponents using the ** operator. For example, 2 ** -3 returns 0.125, which is the same as 1 / (2 ** 3).

Using math.pow()

For floating-point exponents, you can use math.pow(). It always returns a float value, even if both base and exponent are integers. For example, math.pow(2, 3) gives 8.0.
