比较两个 NumPy 数组,如果第一个数组小于等于第二个数组,则返回 True
要比较两个数组,如果一个数组小于等于另一个数组,则返回 True,请在 Python NumPy 中使用 **numpy.char.less_equal()** 方法。arr1 和 arr2 是两个具有相同形状的输入字符串数组。
与 numpy.less_equal 不同,此比较是通过首先从字符串末尾去除空格字符来执行的。此行为是为了与 numarray 保持向后兼容。
numpy.char 模块为类型为 numpy.str_ 或 numpy.bytes_ 的数组提供了一组向量化字符串操作。
步骤
首先,导入所需的库 -
import numpy as np
创建两个字符串的一维数组 -
arr1 = np.array(['Cio', 'Tom', 'Cena', 'Kate', 'Adams', 'brad', 'aa']) arr2 = np.array(['Bella', 'Tom', 'John', 'Kate', 'Amy', 'Brad', 'aaa'])
显示数组 -
print("Array 1...", arr1) print("Array 2...", arr2)
获取数组的类型 -
print("Our Array 1 type...", arr1.dtype) print("Our Array 2 type...", arr2.dtype)
获取数组的维度 -
print("Our Array 1 Dimensions...",arr1.ndim) print("Our Array 2 Dimensions...",arr2.ndim)
获取数组的形状 -
print("Our Array 1 Shape...",arr1.shape) print("Our Array 2 Shape...",arr2.shape)
要比较两个数组,如果一个数组小于等于另一个数组,则返回 True,请使用 numpy.char.less_equal() 方法。arr1 和 arr2 是两个具有相同形状的输入字符串数组 -
print("Result...",np.char.less_equal(arr1,arr2))
示例
import numpy as np # Create two One-Dimensional arrays of string arr1 = np.array(['Cio', 'Tom', 'Cena', 'Kate', 'Adams', 'brad', 'aa']) arr2 = np.array(['Bella', 'Tom', 'John', 'Kate', 'Amy', 'Brad', 'aaa']) # 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 compare and return True if an array is less than equal to another, use the numpy.char.less_equal() method in Python Numpy # The arr1 and arr2 are the two input string arrays of the same shape. print("Result...",np.char.less_equal(arr1,arr2))
