It's a good start, but there are many other differences. a[i] can mean getattr (but usually not), and can throw a KeyError. Similarly, a.b may return null if it doesn't exist, while in Python it will throw an AttributeError. You might need to add uses of global or nonlocal. And there are a lot of other small details.
However, I think it will be much easier than translating the other way around :)
For my use-cases, not much changes between the two -
1. Replace opening and closing braces with colon.
2. Remove semi colons
3. Replace function with def
4. Remove type definitions
5. Replace array manipulation functions with python equivalents.
6. Remove tokens like const, let and var
