import os
os.urandom(24)    # length: 24 bytes, i.e. 24*8=192 bits

See the doc. here.

Formatting its output:

>>> os.urandom(24)
'\x17\x96e\x94]\xa0\xb8\x1e\x8b\xee\xdd\xe9\x91^\x9c\xda\x94\t\xe8S\xa1Oe_'
>>> os.urandom(24).encode('hex')
'cd48e1c22de0961d5d1bfb14f8a66e006cfb1cfbf3f0c0f3'
>>> int(os.urandom(24).encode('hex'), 16)

The code above is for Python 2. Here is the Python 3 version:
