We can see that the constant pi is available simply by accessing the constant in the library. Let’s see how we can import the value: # Using math to Get the Value of Pi Because the math library is part of the standard Python library, you don’t need to install anything additional. In this section, you’ll learn how to use the math library to get the value of pi in Python. Now that you have a good understanding of the nature and uses of pi, let’s see how we can get this important mathematical constant in Python! Get Pi in Python Using Math Understanding how we can calculate Pi with the circumference and diameter of a circle Similarly, the decimal representation of the value never ends and never moves into a permanently repeating pattern. ![]() However, the fraction 22/7 is often used to represent its value as an approximation. Pi itself is an irrational number, meaning that the value cannot be represented as a common fraction. It’s commonly used in Euclidian geometry to represent the ratio of a circle’s circumference to its diameter. The number pi, π, is a mathematical constant that’s approximately equal to 3.14159. Should You Use NumPy or Math to Get Pi in Python?.
