Python Program to Reverse a Tuple 4

Python Program to Reverse Tuple

Write a Python Program to reverse the Tuple items. We used the Tuple slice with a negative value to reverse the numeric, string, mixed, and nested Tuples.

intRTuple = (10, 30, 19, 70, 40, 60)
print("Original Tuple Items = ", intRTuple)

revIntTuple = intRTuple[::-1]
print("Tuple Items after Reversing = ", revIntTuple)

strRTuple = ('apple', 'Mango', 'kiwi')
print("String Tuple Items = ", strRTuple)

revStrTuple = strRTuple[::-1]
print("String Tuple after Reversing = ", revStrTuple)

mixRTuple = ('Apple', 22, 'Kiwi', 45.6, (1, 3, 7), 16, [1, 2])
print("Mixed Tuple Items = ", mixRTuple)

revMixTuple = mixRTuple[::-1]
print("Mixed Tuple after Reversing = ", revMixTuple)
Original Tuple Items =  (10, 30, 19, 70, 40, 60)
Tuple Items after Reversing =  (60, 40, 70, 19, 30, 10)
String Tuple Items =  ('apple', 'Mango', 'kiwi')
String Tuple after Reversing =  ('kiwi', 'Mango', 'apple')
Mixed Tuple Items =  ('Apple', 22, 'Kiwi', 45.6, (1, 3, 7), 16, [1, 2])
Mixed Tuple after Reversing =  ([1, 2], 16, (1, 3, 7), 45.6, 'Kiwi', 22, 'Apple')

In this Python program, we used the reversed function to reverse the Tuple. The reversed function (reversed(intRTuple)) returns the reversed object, so we have to convert it back to Tuple.

intRTuple = (3, 78, 44, 67, 34, 11, 19)
print("Original Tuple Items = ", intRTuple)

revTuple = reversed(intRTuple)
print("Data Type = ", type(revTuple))

revIntTuple = tuple(revTuple)
print("Tuple Items after Reversing = ", revIntTuple)
print("Tuple Data Type = ", type(revIntTuple))
Original Tuple Items =  (3, 78, 44, 67, 34, 11, 19)
Data Type =  <class 'reversed'>
Tuple Items after Reversing =  (19, 11, 34, 67, 44, 78, 3)
Tuple Data Type =  <class 'tuple'>

Python Program to Reverse Tuple using the For loop

In this example, the for loop with reversed function iterates the tuple item from last to first. Within the loop, we are adding each tuple item to revIntTuple.

intRTuple = (10, 19, 29, 39, 55, 60, 90, 180)
print("Original Tuple Items = ", intRTuple)

revintTuple = ()

for i in reversed(range(len(intRTuple))):
    revintTuple += (intRTuple[i],)

print("After Reversing the Tuple = ", revintTuple)
Original Tuple Items =  (10, 19, 29, 39, 55, 60, 90, 180)
After Reversing the Tuple =  (180, 90, 60, 55, 39, 29, 19, 10)

Here, we used for loop range (for i in range(len(intRTuple) – 1, 0, -1)) to iterate tuple items from last to first and add them to reverse Tuple.

intRTuple = (10, 19, 29, 39, 55, 60, 90, 180)
print("Original Tuple Items = ", intRTuple)

revintTuple = ()

for i in range(len(intRTuple) - 1, 0, -1):
    revintTuple += (intRTuple[i],)

print("After Reversing the Tuple = ", revintTuple)
