在Numpy中計算陣列與另一個數組逐元素的邏輯或
要在Python Numpy中計算陣列與另一個數組逐元素的邏輯或,可以使用**numpy.logical_or()**方法。返回值為True或False。返回值是應用於x1和x2元素的邏輯或運算的布林結果;形狀由廣播確定。如果x1和x2都是標量,則這是一個標量。
out是結果儲存到的位置。如果提供,它必須具有輸入廣播到的形狀。如果沒有提供或為None,則返回一個新分配的陣列。元組(只能作為關鍵字引數)的長度必須等於輸出的數量。
步驟
首先,匯入所需的庫:
import numpy as np
使用array()方法建立兩個二維numpy陣列。我們已插入元素:
arr1 = np.array([[True, False, False], [False, True, True]]) arr2 = np.array([[True, False, True], [True, True, False]])
顯示陣列:
print("Array 1...
", arr1)
print("
Array 2...
", arr2)獲取陣列的型別:
print("
Our Array 1 type...
", arr1.dtype)
print("
Our Array 2 type...
", arr2.dtype)獲取陣列的維度:
print("
Our Array 1 Dimensions...
",arr1.ndim)
print("
Our Array 2 Dimensions...
",arr2.ndim)獲取陣列的形狀:
print("
Our Array 1 Shape...
",arr1.shape)
print("
Our Array 2 Shape...
",arr2.shape)要計算陣列與另一個數組逐元素的邏輯或,可以使用numpy.logical_or()方法。返回值為True或False:
print("
Result (OR)...
",np.logical_or(arr1, arr2))示例
import numpy as np
# Creating two 2D numpy array using the array() method
# We have inserted elements
arr1 = np.array([[True, False, False], [False, True, True]])
arr2 = np.array([[True, False, True], [True, True, False]])
# 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 compute the truth value of an array OR another array elementwise, use the numpy.logical_or() method in Python Numpy
# Return value is either True or False
print("
Result (OR)...
",np.logical_or(arr1, arr2))輸出
Array 1... [[ True False False] [False True True]] Array 2... [[ True False True] [ True True False]] Our Array 1 type... bool Our Array 2 type... bool Our Array 1 Dimensions... 2 Our Array 2 Dimensions... 2 Our Array 1 Shape... (2, 3) Our Array 2 Shape... (2, 3) Result (OR)... [[ True False True] [ True True True]]
