Question

Given the following dictionary, what function would you call to access the length of the list [d,e] my_dict?

A. my_dict.size([d, e])
B. my_dict.len([d, e])
C. len(my_dict[d, e])
D. len(my_dict['d', 'e'])

Answer 1

The correct function to access the length of the list [d,e] in the given dictionary is len(my_dict['d', 'e']) option c is the correct.

Step-by-step explanation:

The correct function to access the length of the list [d,e] in the given dictionary would be len(my_dict['d', 'e']).

To access the length of the list [d, e] in the dictionary my_dict, you need to first correctly reference the list within the dictionary by using its key and then call the len function on the list. The correct way to do this, assuming 'd' is a valid key in the dictionary, would be len(my_dict['d']). The correct choice from the options provided would be None of the above, as 'd' should not be combined with 'e' in the key lookup, and the length function is correctly called with just len() and the key used 'd' in square brackets to retrieve the list before determining its length.

In Python, the len() function is used to return the length of an object. In this case, the object is the list [d,e] which is accessed by using the keys 'd' and 'e' in the dictionary my_dict.

Here's an example:

my_dict = {'d': 'value d', 'e': 'value e'}

length = len(my_dict['d', 'e'])

print(length)

This will output 2 which is the length of the list [d,e] in the dictionary my_dict.
