Python中的 numpy.union1d()函数

numpy.union1d()函数查找两个数组的并集,并返回两个输入数组中的任何一个中的唯一、排序的值数组。

代码#1:

# Python program explaining
# numpy.union1d() function
    
# importing numpy as geek 
import numpy as geek 
   
arr1 = [-1, 0, 1]
arr2 = [-2, 0, 2]
   
gfg = geek.union1d(arr1, arr2)
   
print (gfg)

输出 :

[-2 -1  0  1  2]


代码#2:

# Python program explaining
# numpy.union1d() function
    
# importing numpy as geek 
import numpy as geek 
   
arr1 = [-3, -2, -1, 0, 1, 2, 3]
arr2 = [-5, -4, -3, 0, 3, 4, 5]
   
gfg = geek.union1d(arr1, arr2)
   
print (gfg)

输出 :

[-5 -4 -3 -2 -1  0  1  2  3  4  5]
