CODE 1
# Python code to demonstrate working of # reversed() # For string seqString = 'geeks'print(list(reversed(seqString))) # For tuple seqTuple = ('g', 'e', 'e', 'k', 's') print(list(reversed(seqTuple))) # For range seqRange = range(1, 5) print(list(reversed(seqRange))) # For list seqList = [1, 2, 4, 3, 5] print(list(reversed(seqList))) |

CODE 2
vowels = ['a', 'e', 'i', 'o', 'u'] # Function to reverse the list def __reversed__(self): return reversed(self.vowels) # Main Function if __name__ == '__main__': print(list(reversed(vowels))) |
