Return True if x is a not complex type or an array of complex numbers.
The type of the input is checked, not the value. So even if the input has an imaginary part equal to zero, isrealobj evaluates to False if the data type is complex.
The input can be of any type and shape.
The return value, False if x is of a complex type.
Notes
The function is only meant for arrays with numerical values but it accepts all other objects. Since it assumes array input, the return value of other objects may be True.
>>> np.isrealobj('A string')
True
>>> np.isrealobj(False)
True
>>> np.isrealobj(None)
True
Examples
>>> import numpy as np >>> np.isrealobj(1) True >>> np.isrealobj(1+0j) False >>> np.isrealobj([3, 1+0j, True]) False
