You are confusing dynamic typing with weak typing. Weakly typed
languages (such as BASIC perform) such implicit conversions.
However, Python is dynamically and strongly typed.
With dynamic typing, the type information resides with the actual
object and not with the name referring to it. That simply means that
the type cannot be determined till the object is actually created (i.e
till runtime). But once created, the object does have a type.
So you will need to explicitly convert yourself. In this case with
int_value = int(string_value)
