Yes, you would need to add 39.

As py-matplotlib-basemap has no maintainer, this has apparently been missed.

However, when trying to build py39-matplotlib-basemap you will see several errors:

error: no member named 'tp_print' in 'struct _typeobject’

This is no longer supported in Python 3.9. There is no easy workaround to this.
