searching through dictionary with list and string

Question

I have a dictionary(see below) with string as key and list as the values. How can I reference the contents of the list to get the key?

number_dict = {'digits': ['one', 'two', 'three'],
 'tens': ['ten','twenty','thirty','forty'],
'hundreds':['hundred']}

so I tried

if number_dict.values()[0]=="one":
    print(number_dict.key[0])

and I would have expected "digits" as an output.Instead I get:

TypeError: 'dict_values' object is not subscriptable

Answer 1

If it was me I would opt for a List Comprehension :

number_dict = {'digits': ['one', 'two', 'three'],
               'tens': ['ten','twenty','thirty','forty'],
               'hundreds':['hundred']}

[key for key, value in number_dict.items() if 'two' in value]
