30.09.2019 · In your code, you use data.keys () [0] which means: "Give me the first key of the dicitonary". But because the ordering is not guaranteed, asking for the "first" item does not really make sense. This is why in Python 3 it is no longer subscriptable. They prohibit it to prevent logical errors in the code.
