.fiil()

The .fill() method is used to fill a NumPy array with a specified scalar value.

Syntax

ndarray.fill(value)

• ndarray: The NumPy array to be filled.
• value: The scalar value to assign to all the elements in the array.

Example

In this example, the .fill() method assigns the scalar value 2798 to all the elements in the one-dimensional NumPy array nf:

# Import NumPy
import numpy as a

# Create a NumPy array
nf = a.arange(12)

# Use the '.fill()' method
nf.fill(2798)

print(nf)

We will get the following result:

[2798 2798 2798 2798 2798 2798 2798 2798 2798 2798 2798 2798]
