Python Tuple - Slicing Method


The slicing operation on a Python tuple creates another tuple, as specified by the two indexes within the square brackets.

The returned tuple contains the shallow copy of the elements from the original tuple.


Begin Index - Begin index of the tuple object
End Index   - End index + 1 of the tuple object

Default values:

There are different default values assumed in the slicing operation of a tuple.

When BeginIndex is Empty: 0 is assigned as the BeginIndex

When EndIndex is Empty: len(tupleObject) is assigned as the EndIndex

When BeginIndex is Negative: The index is considered relative to the length of the tuple. The specified negative index is added to the len(tuple) to get the actual index.

Invalid Values:

  • If the BeginIndex is greater than EndIndex then the slicing operation results in an empty tuple.

  • If the index is out of bound, it results in an empty slice.

Example1: Slicing with no index speicfied

# Example Python program that returns a slice using the default
# begin index and default end index
fruitBasket = ('Apple', 'Orange', 'Banana', 'Grape', 'Raspberry')
myFruitPlate = fruitBasket[:]
print("Slicing result:")


Slicing result:

('Apple', 'Orange', 'Banana', 'Grape', 'Raspberry')

Example2: With BeginIndex specified

# Slicing operation - 0 to the last index 
stationery  = ('Pen', 'Pencil', 'Notebook', 'Eraser', 'Color pen')
shared = stationery[0:]

# Shared is a shallow copy 



('Pen', 'Pencil', 'Notebook', 'Eraser', 'Color pen')

Example3: With BeginIndex and EndIndex specified covering the whole tuple

# Example Python program that does slicing operation
# on a tuple by specifying the beginning index as 0 and 
# the end index as the total number of elements
playThings  = ("Slide", "Swing", "Seesaw", "Merry-go-round", "Jungle Gym", "Spring Rider")
allPlayThings = playThings[0:len(playThings)]
print("Slicing from 0 to %d:"%len(playThings))


Slicing from 0 to 6:

('Slide', 'Swing', 'Seesaw', 'Merry-go-round', 'Jungle Gym', 'Spring Rider')

Example4: With BeginIndex and EndIndex Specified covering a portion of the tuple

# Example Python program that creates
# a slice of a Python tuple with
# both the beginning and end indexes falling in the middle
# (not the boundary indexes)
timesOfDay  = ("Dawn", "Sunrise", "Morning", "Midday", 
                "Afternoon", "Evening", "Sunset", "Dusk", "Night", "Midnight")
dayTimes    =  timesOfDay[1:6]
print("Resultant slice of the tuple:")


Resultant slice of the tuple:

('Sunrise', 'Morning', 'Midday', 'Afternoon', 'Evening')

Example 5: Slicing by specifying a Negative Index

# Slicing operations with negative indexes
strings = ("Violin", "Viola", "Cello", "Tendor viol", "Double bass")
favs    = strings[2:-1]
print("Favourite string instruments:")



Favourite string instruments:

('Cello', 'Tendor viol')
