Return the truth value of an array less than another element-wise in Numpy
To return the truth value of an array less than another element-wise, use the numpy.less() method in Python Numpy. Return value is either True or False. Returns an output array, element-wise comparison of x1 and x2. Typically, of type bool, unless dtype=object is passed. This is a scalar if both x1 and x2 are scalars.
The condition is broadcast over the input. At locations where the condition is True, the out array will be set to the ufunc result. Elsewhere, the out array will retain its original value. Note that if an uninitialized out array is created via the default out=None, locations within it where the condition is False will remain uninitialized.
Steps
At first, import the required library −
import numpy as np
Creating two 2D numpy array using the array() method. We have inserted elements of int type −
arr1 = np.array([[30, 76, 61], [82, 69, 29]]) arr2 = np.array([[40, 60, 61], [81, 55, 32]])
Display the arrays −
print("Array 1...
", arr1)
print("
Array 2...
", arr2)Get the type of the arrays −
print("
Our Array 1 type...
", arr1.dtype)
print("
Our Array 2 type...
", arr2.dtype)Get the dimensions of the Arrays −
print("
Our Array 1 Dimensions...
",arr1.ndim)
print("
Our Array 2 Dimensions...
",arr2.ndim)Get the shape of the Arrays −
print("
Our Array 1 Shape...
",arr1.shape)
print("
Our Array 2 Shape...
",arr2.shape)To return the truth value of an array less than another element-wise, use the numpy.less() method in Python Numpy. Return value is either True or False −
print("
Result...
",np.less(arr1, arr2))
Example
import numpy as np
# Creating two 2D numpy array using the array() method
# We have inserted elements of int type
arr1 = np.array([[30, 76, 61],
[82, 69, 29]])
arr2 = np.array([[40, 60, 61],
[81, 55, 32]])
# Display the arrays
print("Array 1...
", arr1)
print("
Array 2...
", arr2)
# Get the type of the arrays
print("
Our Array 1 type...
", arr1.dtype)
print("
Our Array 2 type...
", arr2.dtype)
# Get the dimensions of the Arrays
print("
Our Array 1 Dimensions...
",arr1.ndim)
print("
Our Array 2 Dimensions...
",arr2.ndim)
# Get the shape of the Arrays
print("
Our Array 1 Shape...
",arr1.shape)
print("
Our Array 2 Shape...
",arr2.shape)
# To return the truth value of an array less than another elementwise, use the numpy.less() method in Python Numpy
# Return value is either True or False
print("
Result...
",np.less(arr1, arr2))Output
Array 1... [[30 76 61] [82 69 29]] Array 2... [[40 60 61] [81 55 32]] Our Array 1 type... int64 Our Array 2 type... int64 Our Array 1 Dimensions... 2 Our Array 2 Dimensions... 2 Our Array 1 Shape... (2, 3) Our Array 2 Shape... (2, 3) Result... [[ True False False] [False False True]]
