Show a Python dictionary that returns a list ofvalues for each key . The key can be whatever type you want. Design the dictionary so
Show a Python dictionary that returns alist ofvaluesfor eachkey. Thekeycan be whatever type you want.
Design the dictionary so that it could be useful for something meaningful to you. Show at least three different items in it. Invent the dictionary yourself.
Next consider theinvert_dictfunction.
def invert_dict(d):
inverse = dict()
for key in d:
val = d[key]
if val not in inverse:
inverse[val] = [key]
else:
inverse[val].append(key)
return inverse
Modify this function so that it can invert your dictionary. In particular, the function will need to turn each of the list items into separate keys in the
inverted dictionary.
Run your modifiedinvert_dictfunction on your dictionary. Print the original dictionary and the inverted one.
Include your Python program and the output.
Describe what is useful about your dictionary. Then describe whether the inverted dictionary is useful or meaningful, and why.
