Python pi: How to use Pi in Python
Pi is a famous mathematical constant, defined as the ratio of the circumference to the diameter of a circle, and its value is 3.141592653589793. Another popular mathematical constant defined in the math module is e. It is called Euler’s number, and it is a base of the natural logarithm. Its value is 2.718281828459045.
Pi in Python is a math library constant that returns a value of 3.141592653589793. The math.pi constant is defined as the circumference ratio to the diameter of a circle. Mathematically pi is represented by the greek letter π.
It returns a float value that is the value of the mathematical constant “PI“.
import math print('The value of pi is: ', math.pi)
The value of pi is: 3.141592653589793
Python Math Module
Almost all the most essential mathematical methods are defined in the math module of Python. These include trigonometric functions, logarithmic functions, angle conversion functions, representation functions, etc. Also, two mathematical constants are defined in the math module.
Another well-known mathematical constant defined in the math module is e. It is called Euler’s number, and it is base on the natural logarithm. Its value is 2.718281828459045.
The math module in Python contains functions for calculating various trigonometric ratios for the given angle. The functions (sin, cos, tan, etc.) need the angle in radians as an argument. We, on the other side, are using the angle in degrees.
For example, the following code converts the angle of 30 degrees to radians and back (Note: π radians is equivalent to 180 degrees).
import math print(math.degrees(math.pi/6))
These constants in Python math are used to put them into our calculations.
