Python has a standard “math” module that provides different kinds of functions to perform various kinds of mathematical operations. The “math.pow()” function also belongs to the math module’s family and is used to calculate the power of a number. This article will provide you with a de...

Python. You will learn different operations you can use to raise a number to a power. Besides, you will learn how the exponent notation helps write big numbers in a more compact format. Of course, you’ll also learn why there are many ways to calculate exponents and which one you should...
