As no doubt you can see, the last line, indented as it is, does not provide the
output that the book's text says it will return - ie the word 'plants'
If I do not indent it, it returns an 'invalid syntax error' stating that
'producer_entries' is not defined. Though code in the previous line is meant to
do just that - isn't it ?
