Submitted by Pranit Sharma, on January 11, 2023

NumPy is an abbreviated form of Numerical Python. It is used for different types of scientific operations in python. Numpy is a vast library in python which is used for almost every kind of scientific or mathematical operation. It is itself an array which is a collection of various methods and functions for processing the arrays.

## NumPy - Partitioning array into N chunks

Suppose we are given a NumPy array and we need to split it into N chunks.

For this purpose, we will use numpy.array_split() method. It split an array into multiple sub-arrays.

For an array of length L that should be split into n sections, it returns L % n sub-arrays of size : L//n + 1 and the rest of size L//n.

Let us understand with the help of an example,

## Python code for partitioning array into N chunks with NumPy

```# Import numpy
import numpy as np

# Creating an array
arr = np.array([[1,2],[3,4], [5,6], [6,7]])

# Display original array
print("Original Array:\n",arr,"\n")

# Splitting array into 3 parts
res = np.array_split(arr, 3)

# Display result
print("Result:\n",res)
```
