How to calculate pi in Python?

There are several ways to calculate or obtain the value of pi (π) in Python. Here's a breakdown of the methods:

Using the math module

The math module provides direct access to the value of pi.

• Import the math module.
• Access math.pi to get the value.

import math

pi_value = math.pi
print(pi_value)

Using the numpy module

Alternatively, if you're working with numerical computations using numpy, you can access pi through this library as well.

• Import the numpy module.
• Access numpy.pi to get the value.

import numpy as np

pi_value = np.pi
print(pi_value)

Using the radian() function

The radian() function with 180 passed as an argument also returns the value of pi in Python programming language.

import math

pi_value = math.radians(180)
print(pi_value)

In summary, here is a comparison of the methods:

These methods offer simple and accurate ways to retrieve the value of pi within your Python programs, whether for simple calculations or more complex numerical computations.
