Python is a renowned high-level programming language that offers various libraries for a multitude of purposes.
One such library is the Math Library. This library provides mathematical functions, which include the constant Pi (π).
Pi is an important mathematical constant commonly used in trigonometric functions, area, circumference, and volume calculations. In this tutorial, we’ll go through the process of importing π in Python using the Math library.
Step 1: Access Python
You can import Pi in any Python environment, including IDEs like PyCharm and Visual Studio Code, or even Python’s native interpreter, IDLE.
Step 2: Import Math Library
To import Pi, we first need to import the Math library where Pi is defined. This step is considered “calling” the library. Python doesn’t automatically load all existing libraries to save memory; hence we need to manually import the libraries we need.

1 |
import math |
This code gives Python the command to make all the functions within the Math library available to our code.
Step 3: Call Pi
Now that we have the Math library loaded, we can use all its functions, including Pi. When calling Pi, we have to use the prefix ‘math.’ because Pi is defined within the Math library.

1 |
print(math.pi) |
This command will print the value of Pi up to 16 decimal places.
Output
3.141592653589793
Full Code
The full code to import and print the mathematical constant Pi is as follows:

import math print(math.pi) |
Conclusion
Importing mathematical constants and functions in Python is quite convenient with the Math Library. In this tutorial, we went over how to import and call Pi. Once the Math library is imported, using Pi or any other constants or functions is just as easy.
Python’s simplicity and efficiency have made it a fan-favorite amongst programmers worldwide. Stay tuned for more tutorials!
Note: Always remember to import the necessary libraries before calling its functions or constants!
