numpy.unravel_index() function | Python

Last Updated : 22 Apr, 2020

numpy.unravel_index() function converts a flat index or array of flat indices into a tuple of coordinate arrays.

Syntax : numpy.unravel_index(indices, shape, order = 'C') Parameters : indices : [array_like] An integer array whose elements are indices into the flattened version of an array of dimensions shape. shape : [tuple of ints] The shape of the array to use for unraveling indices. order : [{‘C’, ‘F’}, optional] Determines whether the multi-index should be viewed as indexing in row-major (C-style) or column-major (Fortran-style) order. Return : [tuple of ndarray] Each array in the tuple has the same shape as the indices array.

Code #1 :

Python3

# Python program explaining
# numpy.unravel_index() function

# importing numpy as geek 
import numpy as geek

gfg = geek.unravel_index([22, 41, 37], (7, 6))

print(gfg)

Output :

(array([3, 6, 6]), array([4, 5, 1]))

Code #2 :

Python3

# Python program explaining
# numpy.unravel_index() function

# importing numpy as geek 
import numpy as geek

gfg = geek.unravel_index([22, 41, 37], (7, 6), order = 'F')

print(gfg)

Output :

(array([1, 6, 2]), array([3, 5, 5]))

Numpy ndarray.flatten() function in Python

The flatten() function is used to convert a multi-dimensional NumPy array into a one-dimensional array. It creates a new copy of the data so that original array stays unchanged. If your array has rows and columns or even more dimensions, then flatten() line up every single value into a straight list

Numpy recarray.flatten() function | Python

In numpy, arrays may have a data-types containing fields, analogous to columns in a spreadsheet. An example is [(a, int), (b, float)], where each entry in the array is a pair of (int, float). Normally, these attributes are accessed using dictionary lookups such as arr['a'] and arr['b']. Record array

numpy.reshape() in Python

In Python, numpy.reshape() function is used to give a new shape to an existing NumPy array without changing its data. It is important for manipulating array structures in Python. Let's understand with an example:Pythonimport numpy as np # Creating a 1D NumPy array arr = np.array([1, 2, 3, 4, 5, 6])
