numpy.isrealobj()在 Python 中
哎哎哎:# t0]https://www . geeksforgeeks . org/num py-isrealobj-python/
numpy . isralobj(array):这个逻辑函数有助于检查数组是否没有复数类型或者数组是否有复数。即使虚部等于零，也不认为是实物体。
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
