Yes, it has no implicit conversions like JS or R. It does, however, allow you to not specify the type of a variable and even change it without complaining. Even if you add types these are only hints that won't generate errors unless you use external type checking (e.g. mypy).

example:
throws an error because i is double and the list-index expects an integer.
so for it to work the code needs to look like this:
meanwhile this works:
Isn't
//integer division?It is but if you start with a float you get a float back.
You're right, I did not know that. Thanks!
Was really surprised by this too, because iirc Python 2 did not do this.
you can do
i: intto make this error outNo, type hints are not enforced.
