## Creating the array of one's
a = np.ones((1,1))
## creating another array
b = np.arange(4)

## saving both the arrays in the same file using savez as .npz
savez('outfile1',a,b)


## Loading the saved .npz file
npzfile = np.load('outfile1.npz') 

## Checking the files in the .npz file
print (npzfile.files)

#[Output]:
#['arr_1', 'arr_0']


## accessing the content of first file in.npz
print(npzfile['arr_0'])

#[Output]:
#[[1.]]
