NumPy: Compare two given arrays
Compare Two Arrays Element-Wise
Write a NumPy program to compare two arrays using NumPy.
Pictorial Presentation:
Sample Solution:
Python Code:
# Importing the NumPy library with an alias 'np'
import numpy as np
# Creating NumPy arrays 'a' and 'b'
a = np.array([1, 2])
b = np.array([4, 5])
# Displaying the arrays 'a' and 'b'
print("Array a: ", a)
print("Array b: ", b)
# Comparing elements of 'a' and 'b' for greater than operation
print("a > b")
print(np.greater(a, b))
# Comparing elements of 'a' and 'b' for greater than or equal operation
print("a >= b")
print(np.greater_equal(a, b))
# Comparing elements of 'a' and 'b' for less than operation
print("a < b")
print(np.less(a, b))
# Comparing elements of 'a' and 'b' for less than or equal operation
print("a <= b")
print(np.less_equal(a, b))
Sample Output:
Array a: [1 2] Array b: [4 5] a > b [False False] a >= b [False False] a < b [ True True] a <= b [ True True]
Explanation:
In the above code -
a = np.array([1, 2]): A 1D NumPy array a is created with elements [1, 2].
b = np.array([4, 5]): A 1D NumPy array b is created with elements [4, 5].
print(np.greater(a, b)): The np.greater function compares the elements of a and b element-wise and returns a boolean array with the result of the comparison a > b. In this case, the output is [False False].
print(np.greater_equal(a, b)): The np.greater_equal function compares the elements of a and b element-wise and returns a boolean array with the result of the comparison a >= b. In this case, the output is [False False].
print(np.less(a, b)): The np.less function compares the elements of a and b element-wise and returns a boolean array with the result of the comparison a < b. In this case, the output is [True True].
print(np.less_equal(a, b)): The np.less_equal function compares the elements of a and b element-wise and returns a boolean array with the result of the comparison a <= b. In this case, the output is [True True].
