6. Consider this sequence of Python statements... def iSort (x, n=2): return sorted (x, key-lambda a: a[n]) x= [(1, 'one', 'uno'), (2, 'two', 'dos'), (3, 'three', 'tres')] y = iSort (x) z = iSort (x,1) print(x) print (y) print(z) a. Analyze the program to determine the output. b. Check your answer by running the program. c. Make sure you know the difference between the sort() method and the sorted() function
