Python reversed() function
reversed() method returns an iterator that accesses the given sequence in the reverse order.
Syntax :
reversed(sequ)
Parameters :
sequ : Sequence to be reversed.
Returns :
returns an iterator that accesses the given sequence in the reverse order.
CODE 1
# Python code to demonstrate working of# reversed() # For stringseqString = 'geeks'print(list(reversed(seqString))) # For tupleseqTuple = ('g', 'e', 'e', 'k', 's')print(list(reversed(seqTuple))) # For rangeseqRange = range(1, 5)print(list(reversed(seqRange))) # For listseqList = [1, 2, 4, 3, 5]print(list(reversed(seqList))) |
Output :
['s', 'k', 'e', 'e', 'g'] ['s', 'k', 'e', 'e', 'g'] [4, 3, 2, 1] [5, 3, 4, 2, 1]
CODE 2
vowels = ['a', 'e', 'i', 'o', 'u'] # Function to reverse the listdef __reversed__(self): return reversed(self.vowels) # Main Function if __name__ == '__main__': print(list(reversed(vowels))) |
Output :
['u', 'o', 'i', 'e', 'a']
