Today's Learning:

Revision of Python List -Literal 
 

Program No. 1:

# Tuple

# A tuple is a collection which is ordered and unchangeable.

# In Python tuples are written with round brackets.

# Example

# Create a Tuple:

thistuple = ("apple", "banana", "cherry")

print(thistuple)

print(type(thistuple))

Output:

('apple', 'banana', 'cherry')

<class 'tuple'>

Program No. 2:

# Access Tuple Items

# You can access tuple items by referring to the index number,

# inside square brackets:

# Example

# Print the second item in the tuple:

thistuple = ("apple", "banana", "cherry","chiku")

print(thistuple[0:2])

Output:

('apple', 'banana')

Program No. 3:

# Negative Indexing

# Negative indexing means beginning from the end,

# -1 refers to the last item, -2 refers to the second last item etc.

# Example

# Print the last item of the tuple:

thistuple = ("chiku","apple", "banana", "cherry")

print(thistuple[-4])

Output:

chiku

Program No. 4:

# Range of Indexes or Slicing

# You can specify a range of indexes by specifying where

# to start and where to end the range.

# When specifying a range, the return value will be

# a new tuple with the specified items.

# Example

# Return the third, fourth, and fifth item:

# Note: The search will start at index

# 2 (included) and end at index 5 (not included).

# Remember that the first item has index 0.

thistuple = ("apple", "banana", "cherry", "orange", "kiwi", "melon", "mango")

print(thistuple[0:3])

Output:

('apple', 'banana', 'cherry')

Program No. 5:

# Range of Negative Indexes

# Specify negative indexes if

# you want to start the search from the end of the tuple:

# Example

# This example returns the items

# from index -4 (included) to index -1 (excluded)

thistuple = ("apple", "banana", "cherry", "orange", "kiwi", "melon", "mango")

print(thistuple[-10:-1])

Output:

('apple', 'banana', 'cherry', 'orange', 'kiwi', 'melon')

Program No. 6:

# Change Tuple Values

# Once a tuple is created, you cannot change its values.

# Tuples are unchangeable, or immutable.

# But there is a workaround. You can convert the tuple into a list,

# change the list, and convert the list back into a tuple.

# Example

# Convert the tuple into a list to be able to change it:

x = ("apple", "banana", "cherry")

print(x)

print(type(x))

y = list(x)

print(type(y))

print(y)

y[1] = "kiwi"

x = tuple(y)

print(x)

Output:

('apple','kiwi','cherry')
