Generate a variable length hash

Question

Is there a way in python to generate a short version of hashcode, SHA128 or SHA256 I tried this but its not correct way to get[extracting substring to shorten]

hashlib.sha256(str.encode('utf-8')).hexdigest()[:8]

for example if i have a string, i want 8 character hash

str = "iamtestingastringtogethash"
print(hashlib.sha256(str.encode('utf-8').hexdigest(),8))

Output: some_8char_hash

Answer 1

Ok i found my own fix,

hashlib.shake_256(str.encode("utf-8")).hexdigest(length=8)
