可以用 np.polyone() 方法代替np.ones来创建一个元素为1的数组。

语法: np.polyone()
返回：返回数组([1])

例子#1 :

    
# Python program explaining
# numpy.polyone() method 
  
# import numpy and polyone
import numpy as np
from numpy.polynomial.polynomial import polyone
  
# using np.polyone() method
ans = polyone
  
print(ans)

输出 :

[1]

例子#2 :

# Python program explaining
# numpy.polyone() method 
  
# import numpy and polyone
import numpy as np
from numpy.polynomial.polynomial import polyone
  
# using np.polyone() method
ans = polyone + [[1, 3, 5], [2, 4, 6]]
  
print(ans)

输出 :

[[2 4 6]
[3 5 7]]
