How do I get a specific value from a key in a dictionary with multiple values per key?

I have a dictionary in this format:

my_dict = {"key1":["value1", "value2", "value3"]}

Is there an easy way to get key1's third value? I guess I could get the whole list of values and then split it up, but there must be a better way

I prefer to use get i.e. my_dict.get('key1')[2]

If you use my_dict['key1'][2] , you will get a KeyError if key1 is not present in my_dict

Example -

>>> d = {1:3,4:6}
>>> d.get(7) # No Error
>>> d[7] 
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
KeyError: 7

You can do a simple look up in the following ways -

my_dict['key1'][2]

#Output = 'value3'

OR (using dict.get)

my_dict.get('key1')[2]

#Output = 'value3'

OR (if you want 3rd element without specifying the key)

list(my_dict.values())[0][2]

#Output = 'value3'

OR (if you want last element without specifying the key)

list(my_dict.values())[0][-1]

#Output = 'value3'
