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))) 

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 list 
def __reversed__(self): 
    return reversed(self.vowels) 
  
# Main Function     
if __name__ == '__main__': 
    print(list(reversed(vowels))) 

Output :

['u', 'o', 'i', 'e', 'a']
