Python numpy.less()

Python numpy.less() :检查x1是否小于x2。

语法 :

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

参数 :

x1, x2 : [array_like]输入数组。如果x1.shape != x2.shape，它们必须可以广播到一个共同的形状。
out : [ndarray, boolean]布尔数组，如果x1和x2是标量，则是单个布尔。

返回 :

表示结果的布尔数组，即X1是否小于X2。

代码 1 :

# Python Program illustrating
# numpy.less() method
  
import numpy as geek
 
a  = geek.less([8., 2.], [5., 3.])
print("Not equal : \n", a, "\n")
 
b = geek.less([2, 2], [[1, 3],[1, 4]])
print("Not equal : \n", b, "\n")
 
a = geek.array([4,2])
b = geek.array([6,2])
 
print("Is a lesser than b : ", a < b)

输出 :

Not equal : 
 [False  True] 

Not equal : 
 [[False  True]
 [False  True]] 

Is a lesser than b :  [ True False]]

代码 2 :

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

输出 :

Comparing complex with int :  [ True False]

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

代码 3 :

# Python Program illustrating
# numpy.less() method
   
import numpy as geek
 
# Here we will compare Float with int values
a = geek.array([1.1, 1])
b = geek.array([1, 2])
  
# indicating 1.1 is greater than 1
print("Comparing float with int : ", a < b)
 
# indicating 1.1 is greater than 1
d  = geek.less(a, b)
print("\n Comparing float with int using  .less() : ", d)

输出 :

Comparing float with int :  [False  True]

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