What is equivalent of Matlab nan( ) in python?

this is my MATLAB code with the following output:

pad=nan(1,5)

pad =

   NaN   NaN   NaN   NaN   NaN

I want to do the same operation in python, I tried np.isnan(1,6) but this is not working. what should I used to get the same results. thank you

>Solution :

You can use np.full() to create a multi-dimensional array pre-populated with the same values:

np.full((1, 5), np.nan)

which produces:

array([[nan, nan, nan, nan, nan]])
