numpy.isreal(array) : Test element-wise whether it is a real number or not(not infinity or not Not a Number) and return the result as a boolean array.
Parameters :
array : [array_like] Input array whose element we want to test
Return :
boolean array containing the result
Code 1 :
Python
# Python Program illustrating # numpy.isreal() method import numpy as geek
print ( "Is Real : " , geek.isreal([ 1 + 1j , 0j ]), "\n" )
print ( "Is Real : " , geek.isreal([ 1 , 0 ]), "\n" )
|
Output :
Is Real : [False True] Is Real : [ True True]
Code 2 :
Python
# Python Program illustrating # numpy.isreal() method import numpy as geek
# Returns True/False value for each element a = geek.arange( 20 ).reshape( 5 , 4 )
print ( "Is Real : \n" , geek.isreal(a), "\n" )
# Returns True/False value as ans # because we have mentioned dtype in the beginning a = geek.arange( 20 ).reshape( 5 , 4 ).dtype = float
print ( "\nIs Real : " , geek.isreal(a))
|
Output :
Is Real : [[ True True True True] [ True True True True] [ True True True True] [ True True True True] [ True True True True]] Is Real : True
