NumPy: Rearrange the dimensions of a given array
NumPy: Array Object Exercise-126 with Solution
Write a NumPy program to rearrange array dimensions.
Sample Solution:
Python Code:
# Importing the NumPy library and aliasing it as 'np'
import numpy as np
# Creating a NumPy array 'x' with elements from 0 to 23 using np.arange() and reshaping it to a 6x4 array
x = np.arange(24).reshape((6, 4))
# Printing a message indicating the original array will be displayed
print("Original array:")
print(x) # Displaying the original 6x4 array 'x'
# Transposing the array 'x' to reverse its dimensions using np.transpose()
new_array = np.transpose(x)
# Printing a message indicating the array after reversing the dimensions will be displayed
print("After reversing the dimensions:")
# Displaying the transposed array 'new_array'
print(new_array)
Sample Output:
Original arrays: [[ 0 1 2 3] [ 4 5 6 7] [ 8 9 10 11] [12 13 14 15] [16 17 18 19] [20 21 22 23]] After reverse the dimensions: [[ 0 4 8 12 16 20] [ 1 5 9 13 17 21] [ 2 6 10 14 18 22] [ 3 7 11 15 19 23]]
Explanation:
x = np.arange(24).reshape((6,4)): This line creates an array with values from 0 to 23 (24 values) using np.arange(24), and then reshapes it into a 6x4 array using reshape((6,4)).
new_array = np.transpose(x): It transposes the 6x4 x array by swapping its rows and columns
Finally, printf() prints the transposed new_array.
