# numpy.isrealobj() in Python

numpy.isrealobj(array) : This logical function helps to checks if the array has no complex type or array has a complex number. Even if imaginary part is equal to zero, it is not considered to be a Real Object.

Parameters :

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

Return :

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

Code 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) `

Output :

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

Is real :  True
```

Code 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)) `

Output :

```Is real :  True

class 'complex'

Is real :  True

Is real :  False```
