Python numpy.isrealobj()用法及代码示例


numpy.isrealobj(array):此逻辑函数有助于检查数组是否没有复杂类型或数组是否具有复杂数字。即使虚部等于零,也不会将其视为实物。

参数:

array   :[array_like]Input array or object whose elements, we need to test.

返回:


True, if the input array hasn't any complex element; otherwise False 


代码1:

# Python program explaining 
# isrealobj() function 
import numpy as np 
  
in_array = [1, 3, 5, 4] 
print ("Input array:", in_array) 
  
output_value = np.isrealobj(in_array) 
print ("\nIs real:", output_value)

输出:

Input array: [1, 3, 5, 4]

Is real: True


代码2:

# Python Program illustrating 
# numpy.isrealobj() method    
import numpy as geek  
     
# Returns True/False value for each element  
a = geek.arange(20).reshape(5, 4) 
print("Is real:", geek.isrealobj(a)) 
     
# Returns True/False value as ans  
# because we have mentioned dtpe in the beginning 
b = geek.arange(20).reshape(5, 4).dtype = complex
                   
print("\n",b) 
print("\nIs real:", geek.isrealobj(b)) 
    
    
b = [[1j],  
     [3]] 
print("\nIs real:", geek.isrealobj(b))

输出:

Is real: True

 class 'complex'

Is real: True

Is real: False
