[Python] Making a dir using uuid as a directory in python 3

import os
import uuid

wallet_filepath = os.path.join( 'PWD', str(uuid.uuid4().hex) , '.bin')
print (wallet_filepath)
print (os.path.exists(wallet_filepath))
print (os.stat(wallet_filepath))


This is the OUTPUT that I am getting from this code.

/home/user/randomTests/b1c51a61c235479aa0964e14db7135d6/.bin

False

Traceback (most recent call last):
File "testDir.py", line 9, in <module>
