Converting byte array/MySQL BLOB to list/Numpy array of float32 in Python?

Question

I have a list of float32 numbers stored as BLOB on MySQL, I have the following script to read it from my database, it looks like mydata is of type bytearray, how can I convert it to a list or Numpy array of type float32?

query = ("SELECT mydata FROM mytable LIMIT 0,100")
cursor.execute(query)

for (mydata,) in cursor:
    print mydata  # bytearray(b"\xbe\xefe\x00#\xdf\x10\x...

Thanks!

np.frombuffer(mydata, dtype=np.float32) seems to work.
