How to create a null vector in numpy?
How to create a null vector in numpy?
This recipe helps you create a null vector in numpy
Recipe Objective
Null array comes quite handy while operating with numpy library in python.
So this recipe is a short example on how to create a null vector with size n in numpy. Let's get started.
Step 1 - Import the library
import numpy as np
Let's pause and look at these imports. Numpy is generally helpful in data manipulation while working with arrays. It also helps in performing mathematical operation.
Step 2 - Defining null_array function
def null_array(n):
x=np.zeros(n)
return x
We have a created a function which will produce an n sized 0 vector.
Step 3 - Printing array
print(null_array(10))
We call the null_array function of size 10.
Step 4 - Lets look at our dataset now
Once we run the above code snippet, we will see:
[0. 0. 0. 0. 0. 0. 0. 0. 0. 0.]
