 Hi, let's talk how to get and use Pconstant in Python programming language. Pyconstant is mathematical constant, so if we want to use it, we need to import matmodule. And inside our matmodule, we have that constant if we type mat.py, we will get the value of Pconstant. If you want to use it in further calculations, for example, you can store this value inside some variable or you can use it everywhere by calling matmodule. For example, if you want to calculate 2 times P, you just will type 2 times P and you will get the result. Same thing is if you type 2 times mat.py, we will get the same result. That's all in this lesson. Thanks for watching. Bye-bye.
