numpy.equal(arr1,arr2,out = None,where = True,cast ='same_kind',order ='K',dtype = None,ufunc'not_equal'):此逻辑函数检查arr1 == arr2 elemen-twise。
参数:
-
arr1 :[数组]输入数组
arr2 :[数组]输入数组 - out :[ndarray,可选]输出数组,其尺寸与输入数组相同,并放置在结果中。
- **kwargs:允许您将关键字的可变参数长度传递给函数。当我们要处理函数中的命名参数时使用它。
- where :[数组,可选] True值表示在该位置计算通用函数(ufunc),False值表示将值保留在输出中。
返回:
Returns arr1 == arr2 element-wise
代码1:
# Python Program illustrating
# numpy.equal() method
import numpy as geek
a = geek.equal([1., 2.], [1., 3.])
print("Check to be Equal:\n", a, "\n")
b = geek.equal([1, 2], [[1, 3],[1, 4]])
print("Check to be Equal:\n", b, "\n")
输出:
Check to be Equal: [ True False] Check to be Equal: [[ True False] [ True False]]
代码2:使用.equal()函数比较数据类型
# Python Program illustrating
# numpy.equal() method
import numpy as geek
# Here we will compare Complex values with int
a = geek.array([0 + 1j, 2])
b = geek.array([1,2])
d = geek.equal(a, b)
print("Comparing complex with int using .equal():", d)
输出:
Comparing complex with int using .equal(): [False True]
代码3:
# Python Program illustrating
# numpy.not_equal() method
import numpy as geek
# Here we will compare Float with int values
a = geek.array([1.1, 1])
b = geek.array([1, 2])
d = geek.not_equal(a, b)
print("\nComparing float with int using .not_equal():", d)
输出:
Comparing float with int using .not_equal(): [ True True]
