You need to join the fields and the field types. Use zip().

Then join with commas.

fields_and_types = ['%s %s' % (field, type) for field, type in zip(fields,
types)]

what_goes_between_the_parens = ', '.join(fields_and_types)

sql = 'create table %s (%s)' % (tablename, what_goes_between_the_parens)

See where that gets you.
