Question

I want to generate a fixed-length (say 10 characters) hash based on current date & time. This hash will be append to names of the uploaded files from my users. How can I do that in Python?

Answer 1

Batteries included:

Python3

import hashlib
import time

hashlib.sha1().update(str(time.time()).encode("utf-8"))
print(hashlib.sha1().hexdigest())
print(hashlib.sha1().hexdigest()[:10])

Python2

import hashlib
import time

hash = hashlib.sha1()
hash.update(str(time.time()))
print hash.hexdigest()
print hash.hexdigest()[:10]
