給定直角三角形的兩條直角邊,用Python返回它的斜邊。
要獲得斜邊,請在Python NumPy中使用numpy.hypot()方法。該方法返回三角形(s)的斜邊。如果x1和x2都是標量,則這是一個標量。此方法等效於sqrt(x1**2 + x2**2),逐元素計算。如果x1或x2是標量型別,則將其廣播以用於另一個引數的每個元素。引數是三角形(s)的直角邊。如果x1.shape != x2.shape,則它們必須可以廣播到公共形狀。
步驟
首先,匯入所需的庫:
import numpy as np
建立一個包含整數元素的陣列:
arr = np.ones((3, 3), dtype=int)
顯示我們的陣列:
print("Array...\n",arr)
獲取資料型別:
print("\nArray datatype...\n",arr.dtype)
獲取陣列的維度:
print("\nArray Dimensions...\n",arr.ndim)
獲取陣列的元素個數:
print("\nNumber of elements in the Array...\n",arr.size)
獲取斜邊:
print("\nHypotenuse..\n",np.hypot((3*arr), (4*arr)))
示例
import numpy as np # To get the hypotenuse, use the numpy.hypot() method in Python Numpy. # The method returns the hypotenuse of the triangle(s). This is a scalar if both x1 and x2 are scalars. # This method is equivalent to sqrt(x1**2 + x2**2), element-wise. If x1 or x2 is scalar_like, it is broadcast for use with each element of the other argument. # The parameters are the leg of the triangle(s). If x1.shape != x2.shape, they must be broadcastable to a common shape. # Creating an array with integer elements arr = np.ones((3, 3), dtype=int) # Display the array print("Array...\n", arr) # Get the type of the array print("\nOur Array type...\n", arr.dtype) # Get the dimensions of the Array print("\nOur Array Dimensions...\n",arr.ndim) # Get the number of elements in the Array print("\nNumber of elements...\n", arr.size) # Get the hypotenuse print("\nHypotenuse..\n",np.hypot((3*arr), (4*arr)))
輸出
Array... [[1 1 1] [1 1 1] [1 1 1]] Our Array type... int64 Our Array Dimensions... 2 Number of elements... 9 Hypotenuse.. [[5. 5. 5.] [5. 5. 5.] [5. 5. 5.]]
