Tuples +, *, and slicing operations return new tuples.
To sort a tuple, convert it to a list to gain access to a sorting method call, or use the sorted built-in that accepts any sequence object.
T = ('cc', 'aa', 'dd', 'bb') tmp = list(T) # Make a list from a tuple's items tmp.sort() # Sort the list print( tmp ) T = tuple(tmp) # Make a tuple from the list's items print( T ) print( sorted(T) ) # Or use the sorted built-in, and save two steps # from www. j a v a 2s. c o m
Here, the list and tuple built-in functions are used to convert the object to a list and then back to a tuple.
