## How do you use PI in NumPy Python?

The following is the syntax:

1. # using numpy. # value of pi. np.py. # using math.
2. # get pi constant value. print(np.pi) import numpy as np # get pi constant value print(np.pi)
3. import math. # get pi constant value. print(math.pi)
4. import math. # check if value of pi from both the libraries is equal. if math.pi == np.pi:

## How do you use PI in Python?

Use Pi in Python

1. Use the math.pi() Function to Get the Pi Value in Python.
2. Use the numpy.pi() Function to Get the Pi Value in Python.
3. Use the scipy.pi() Function to Get the Pi Value in Python.
4. Use the math.radians() Function to Get the Pi Value in Python.

What does NP pi do?

pi provides us with the same value, the advantage of numpy. pi is that it helps us by avoiding the dependency of obtaining the constant value of pi from a different library.

### Is pi stored in Python?

As you can see, the pi value is given to fifteen decimal places in Python. The number of digits provided depends on the underlying C compiler. Python prints the first fifteen digits by default, and math. pi always returns a float value.
