Question

I already referred to the docs, but I can’t seem to extract this associative-array or dictionary:

# errors = session.pop('_flashes')
# repr(errors)
[('message', [u'Content is empty'])]

when I Do:

repr(errors['message'])

I’m getting an error instead:

TypeError: list indices must be integers, not str

What am I doing wrong?

Answer 1

errors = [('message', [u'Content is empty'])]

is not a dict. It is a list of tuple(s).

You can convert it to dict easily:

d = dict(errors)

d contains now {'message': [u'Content is empty']}

and access its elements:

d['message']

returns [u'Content is empty']

or directly down to the string:

d['message'][0]

returns u'Content is empty'
