Is there any module in Python for generating random strings? [duplicate]

Question

Is there any module in Python for generating random strings but to be unique ? I need to generate keys like for example when installing Windows.

to generate a random bytestring (not necessarily unique), you could use os.urandom(size). ssl.RAND_bytes(size) (Python 3.3) provides cryptographically strong pseudo-random bytes. — jfs

Since you haven't specified the format of the string you want to get, I suppose it doesn't matter, so I suggest simply using UUIDs.

>>> import uuid
>>> str(uuid.uuid4())
  > '3afc84bb-6d73-4482-806a-6b3a29e43bca'

Well if you want only letters, for example, here's code to generate a random string of a random length upto 1000:

out = ''
for i in range(random.random()*100):
    out += random.choice('ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvqxyz')

You can modify your alphabet of course.
