Implement a group_by_owners function that:
-
Accepts a dictionary containing the file owner name for each file name.
-
Returns a dictionary containing a list of file names for each owner name, in any order.
For example, for dictionary {‘Input.txt’: ‘Randy’, ‘Code.py’: ‘Stan’, ‘Output.txt’: ‘Randy’} the group_by_owners function should return {‘Randy’: [‘Input.txt’, ‘Output.txt’], ‘Stan’: [‘Code.py’]}.
Difficulty : Easy
Time : 10min
class FileOwners:
@staticmethod
def group_by_owners(files):
owner_dict = dict()
owner_book = list()
for key, value in files.items():
temp = [value, key]
owner_book.append(temp)
for i in owner_book:
if i[0] not in owner_dict:
owner_dict[i[0]] = [i[1]]
else:
owner_dict[i[0]].append(i[1])
return owner_dict
files = {
'Input.txt': 'Randy',
'Code.py': 'Stan',
'Output.txt': 'Randy'
}
print(FileOwners.group_by_owners(files))
