Accessing Identifiers values with python

[Nicolas.Laurent]

A newbie's question.

How do I list the different values in the identifiers field?
I can access a given value (ISBN in this case) using the code below, but I'd like to access all the values.

Thanks in advance.

python:
def evaluate(book, context):
	isbn = book.get('identifiers').get('isbn', '')

python:
def evaluate(book, context):
    res = ''
    for k, v in book.get('identifiers').items():
        res += f'{k}: {v}\n'
    return res

Perfect!
