Hi I have a dictionary that contains data like this

dict = {'file1.txt': ['A', 'B' , 'C' , 'D' , 'E' ] , 'file2.txt': ['A', 'F' , 'C' , 'G' , 'E' ] , 'file3.txt': ['T', 'F' , 'C']}

Could some one please help me write a code that could remove the duplicate values and change the file to

dict = {'file1.txt': ['B' , 'D' ] , 'file2.txt': [ 'G' ] , 'file3.txt': [ 'T' ]}

(only the unique values...
