NumPy: Create and display every element of a numpy array
Display Every Array Element
Write a NumPy program to create and display every element of a NumPy array.
Sample Solution:
Python Code:
# Importing the NumPy library and aliasing it as 'np'
import numpy as np
# Creating a 1-dimensional array 'x' with values from 0 to 11 and reshaping it into a 3x4 array
x = np.arange(12).reshape(3, 4)
# Using a loop with np.nditer to iterate through each element in the array 'x' regardless of its dimension
# Printing each element followed by a space and keeping the output in the same line due to the 'end' parameter
for x in np.nditer(x):
print(x, end=' ')
# Printing a newline character to move to the next line after the loop completes
print()
Sample Output:
0 1 2 3 4 5 6 7 8 9 10 11
Explanation:
In the above code –
‘x = np.arange(12).reshape(3, 4)’ creates a 1D NumPy array with elements from 0 to 11 using np.arange(), and then reshapes it into a 3x4 array using reshape(3, 4) and stores it in the variable ‘x’.
for x in np.nditer(x):: This line iterates through each element in the reshaped array using np.nditer(). np.nditer() is a NumPy iterator object that allows efficient iteration over elements in a NumPy array.
print(x, end=' '): Inside the loop, this line prints the current element followed by a space (the end=' ' argument ensures that the elements are printed on the same line separated by spaces)
