If you want to do all by yourself you can create a list of starting
positions, and you can add None to it, so you can use it to slice a
line with a loop.
You can also create a list of types, so you can cast the string parts
to their correct types, catching the exceptions. You can do it in a
second loop for clarity, or the first one to speed up a bit.
So you can just create a list of data for each input line, a dict may
be unnecessary because the number of fields seems fixed.
