No there is not. You cannot declare a variable or value as constant in Python. Just don't change it.
If you are in a class, the equivalent would be:
class Foo(object): CONST_NAME = "Name"
if not, it is just
CONST_NAME = "Name"
But you might want to have a look at the code snippet Constants in Python by Alex Martelli.
As of Python 3.8, there's a
typing.Final variable annotation that will tell static type checkers (like mypy) that your variable shouldn't be reassigned. This is the closest equivalent to Java's
final. However, it does not actually prevent reassignment :
from typing import Final a: Final = 1 # Executes fine, but mypy will report an error if you run mypy on this: a = 2
