Question

I’m wanting to create a Mapping like so:

assets = {'first': ['type1','type2','type3'], 'second': ['type1','type2']}

Just a simple Mapping (associative array). I’m not sure if the syntax above is correct (new to python), but that is the idea I’m going for.

Now, I want to be able to loop through the mapping:

for key, value in assets:

But that returns an error:

ValueError: too many values to unpack

How can I go about doing this?

Answer 1

Try:

for key, value in assets.items():

The default iterator for a dict is just the key values. The use of items() produces a sequence of (key, value) tuples.
