No worries, everyone starts somewhere! In Python, you can find the length or number of items in a dictionary value using the len() function. However, in your example, the dictionary value is a list, so you'll need to access the list first and then use len() on it. Here's how you can do it:
d = {'key': ['hello', 'brave', 'morning', 'sunset', 'metaphysics']}
#Access the list value using the key
value_list = d['key']
# Find the length of the list
length = len(value_list)
# Print the length
print(length)
In this code, the dictionary d has a key-value pair where the value is a list. By accessing the list using the key 'key', we assign it to the variable value_list. Then, we use len() on value_list to find the length or number of items in the list. Finally, we print the length using the print() function.
