NumPy: Test comparison operators
NumPy String: Exercise-14 with Solution
Write a NumPy program to test equal, not equal, greater equal, greater and less test of all the elements of two given arrays.
Sample Solution:-
Python Code:
import numpy as np
x1 = np.array(['Hello', 'PHP', 'JS', 'examples', 'html'], dtype=np.str)
x2 = np.array(['Hello', 'php', 'Java', 'examples', 'html'], dtype=np.str)
print("\nArray1:")
print(x1)
print("Array2:")
print(x2)
print("\nEqual test:")
r = np.char.equal(x1, x2)
print(r)
print("\nNot equal test:")
r = np.char.not_equal(x1, x2)
print(r)
print("\nLess equal test:")
r = np.char.less_equal(x1, x2)
print(r)
print("\nGreater equal test:")
r = np.char.greater_equal(x1, x2)
print(r)
print("\nLess test:")
r = np.char.less(x1, x2)
print(r)
Sample Input:
['Hello' 'PHP' 'JS' 'examples' 'html'] ['Hello' 'php' 'Java' 'examples' 'html']
Sample Output:
Array1: ['Hello' 'PHP' 'JS' 'examples' 'html'] Array2: ['Hello' 'php' 'Java' 'examples' 'html'] Equal test: [ True False False True True] Not equal test: [False True True False False] Less equal test: [ True True True True True] Greater equal test: [ True False False True True] Less test: [False True True False False]

Debug With the Print() Function:
>>> for i in range(5): ... print(i, end=', ' if i < 4 else '\n') ... 0, 1, 2, 3, 4 >>> for i in range(5): ... print(f'{i} & {i*i}', end=', ' if i < 4 else '\n') ... 0 & 0, 1 & 1, 2 & 4, 3 & 9, 4 & 16
