'too many values to unpack', iterating over a dict. key=>string, value=>list

Question

I am getting the 'too many values to unpack' error. Any idea how I can fix this?

first_names = ['foo', 'bar'] 

last_names = ['gravy', 'snowman'] 

fields = { 

'first_names': first_names, 

'last_name': last_names, 

} 

for field, possible_values in fields: # error happens on this line

Answer 1

You need to use something iteritems.

for field, possible_values in fields.iteritems(): 

print(field, possible_values)

Answer 2

You can try using something like iteritems.

for field, possible_values in fields.iteritems():

   print field, possible_values

If you are working on Python 3 try using items() instead of using iteritems().

for field, possible_values in fields.items():

    print(field, possible_values)
