Python numpy.equal()用法及代碼示例

numpy.equal(arr1,arr2,out = None,where = True,cast ='same_kind',order ='K',dtype = None,ufunc'not_equal'):此邏輯函數檢查arr1 == arr2 elemen-twise。

參數:

  • arr1 :[數組]輸入數組
    arr2 :[數組]輸入數組

  • out :[ndarray,可選]輸出數組,其尺寸與輸入數組相同,並放置在結果中。
  • **kwargs:允許您將關鍵字的可變參數長度傳遞給函數。當我們要處理函數中的命名參數時使用它。
  • where :[數組,可選] True值表示在該位置計算通用函數(ufunc),False值表示將值保留在輸出中。

返回:

Returns arr1 == arr2 element-wise


代碼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")

輸出:

Check to be Equal:
 [ True False] 

Check to be Equal:
 [[ True False]
 [ True False]] 


代碼2:使用.equal()函數比較數據類型

# 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)

輸出:

Comparing complex with int using .equal(): [False  True]


代碼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)

輸出:

Comparing float with int using .not_equal(): [ True  True]
