Python中的 numpy.less_equal()

numpy.less_equal()函数检查 x1 是否 <= x2。

句法 ：

numpy.less_equal(x1, x2[, out])

参数 ：

x1, x2 : [array_like]Input arrays. If x1.shape != x2.shape, they must be 
             broadcastable to a common shape 
out    : [ndarray, boolean]Array of bools, or a single bool if x1 and x2 are scalars.

返回 ：

Boolean array indicating results, whether x1 is lesser than x2 or not.

代码 1：

# Python Program illustrating
# numpy.less_equal() method
   
import numpy as geek 
  
a  = geek.less_equal([8., 2.], [5., 3.])
print("less_equal() : \n", a, "\n")
  
b = geek.less_equal([2, 2], [[1, 3],[1, 4]])
print("less_equal() : \n", b, "\n")
  
a = geek.array([4,3])
b = geek.array([6,2])
  
print("Is a less_equal than b : ", a <= b)

输出 ：

less_equal() : 
 [False  True] 

less_equal() : 
 [[False  True]
 [False  True]] 

Is a less_equaler than b :  [ True False]

代码 2：

# Python Program illustrating
# numpy.less_equal() method
    
import numpy as geek 
   
# Here we will compare Complex values with the 
a = geek.array([100j,7])
b = geek.array([1,2])
   
print("Comparing complex with int : ", a <= b)
  
d  = geek.less_equal(a, b)
print("\n Comparing complex with int  .less_equal() : ", d)

输出 ：

Comparing complex with int :  [ True False]

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

代码 3：

# Python Program illustrating
# numpy.less_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])
  
print("Comparing float with int : ", a <= b)
  
d  = geek.less_equal(a, b)
print("\n Comparing float with int using  .less_equal() : ", d)

输出 ：

Comparing float with int :  [False  True]

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