Writing some floats in a file in an efficient way

struct.pack() as advised works fine.
Exemple:

 >>> import struct
 >>> struct.pack(">d", -0.0)
b'\x80\x00\x00\x00\x00\x00\x00\x00'

before I read your answers I found a way
with pickle

 >>> import pickle
 >>> pickle.dumps(-0.0)[3:-1]
b'\x80\x00\x00\x00\x00\x00\x00\x00'

but struct.pack() is better
Thx
