Way to loop np.save or np.savetxt?

I have very large data sets and so need to save by appending parts. The simplified version is below and I’m not sure why it doesn't work:

number = 10 #the number of iterations
thing = np.array(1,2,3)

f = open('a.npy', 'ab') #open a file for appending
for i in range(number):
np.save(f, thing) #save the thing to a file

with open('a.npy', 'rb') as f: #open a file for reading
a = np.load(f)
print(a) #this just returns 1,2,3 (not this ten times which is what I want).


I.e. I want to return [1,2,3,1,2,3,1,2,3,...,1,2,3]
