Answer for learning journal #7

# name : [animal type, age, sex]

animal_shellter = {

"Teddy": ["dog",4,"male"],

"Elvis": ["dog",1,"male"],

"Sheyla": ["dog",5,"female"],

"Topic": ["hamster",3,"male"],

"Kuzya": ["cat",10,"male"],

"Misi": ["cat",8,"female"], }

print(animal_shellter)

print("")

def invert(d):

inverse = dict()

for key in d:

val = d[key]

for item in val:

if item not in inverse:

inverse[item] = [key]

else:

inverse[item].append(key)

return inverse

inverted_shellter = invert(animal_shellter)

print(inverted_shellter)

The Inverted dictionary is very useful becasue It give data for this problem.

NOW, here is the question:

Modify your program from Learning Journal Unit 7 to read dictionary items from a file and write the inverted dictionary to a file. You will need to decide on the following:

• How to format each dictionary item as a text string in the input file.
• How to covert each input string into a dictionary item.
• How to format each item of your inverted dictionary as a text string in the output file.

Create an input file with your original three-or-more items and add at least three new items, for a total of at least six items.

Include the following in your Learning Journal submission:

• The input file for your original dictionary (with at least six items).
• The Python program to read from a file, invert the dictionary, and write to a different file.
• The output file for your inverted dictionary.
• A description of how you chose to encode the original dictionary and the inverted dictionary in text files.
