if the structure does not change all the time you could use the renaming of columns in a more automated way like described here.

But this example does not handle nested columns.

You could also try to create a schema without spaces and pass that when you read the data.

This can be done manually or programatically (although this can be a challenge for deeply nested structures).

The second method seems better imo. As the schema method returns a nested list/array/...

Python and Scala have quite some collection parsing possibilities. Also the fact that the StructField type has an attribute called 'name' is useful.
