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:

i = 5.0//2

list[i]

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:

i = int(5.0//2)

list[i]

meanwhile this works:

i=5

i= ‘abcde’

No, type hints are not enforced.

It is but if you start with a float you get a float back.
