Splitting a dictionary's multiple values from one key

I have the dictionary:

dict1 = {'A': {'val1': '5', 'val2': '1'},
  'B': {'val1': '10', 'val2': '10'},
  'C': {'val1': '15', 'val3': '100'}

Here, I have one key, with two values. I can obtain the key by using:

letters = dict1.keys()

which returns:

 ['A', 'B', 'C']

I am use to working with arrays and being able to "slice" them. How can I break this dictionary in a similar way as the key for the values?

 val1_and_val2 = dict1.values()

returns:

 [{'val1': '5', 'val2': '1'},
{'val1': '10', 'val2': '10'},
{'val1': '15', 'val2': '100'}]

How can I get:

 number1 = [5, 10, 15]
 number2 = [1, 10, 100]

If I understand you correctly then:

number1 = [val["val1"] for val in dict1.values()]

If you prefer, this will accomplish the same thing with lambdas.

number1 = map(lambda value: value["val1"], dict1.values())

Note how you really need to take the dict1[key]["val1"] to get an individual value.
