Just like lists, the items in a tuple are assigned an index, which allows you to access individual elements. Every item in a tuple has a unique index based on its position. Indexing starts at [0], meaning the first item has an index of [0], the second item has an index of [1], the third item has an index of [2], and so on. You can use these indexes to retrieve any specific item from the tuple.  

country = ("Spain", "India", "US", "Germany")
#            [0]      [1]     [2]    [3]
            

Accessing tuple items:

1. Positive Indexing:

As we have seen that tuple items have an index, we can access items using these indexes.

Example:

country = ("Spain", "India", "US", "Germany")
print(country[0])
print(country[3])
print(country[2])
            

Output:

Spain
US
Germany

            

2. Negative Indexing:

Similar to positive indexing, negative indexing is also used to access items, but from the end of the tuple. The last item has index [-1], the second last item has index [-2], the third last item has index [-3], and so on.

Example:

country = ("Spain", "India", "US", "Germany")
print(country[0])
print(country[3])
print(country[2])
            

Output:

Germany
India
US
            

3. Range of Index (Tuple Slicing)

Instead of accessing a single item, you can access multiple items from a tuple by specifying a range of indexes. This is called tuple slicing.

Syntax:

Tuple[start : end : step]
            

• start specifies the index where the slice begins (inclusive).
• end specifies the index where the slice ends (exclusive).
• The item at the end index is not included in the result.
• step The number of positions to move between items. It is optional, and the default value is 1.

Example:

country = ("Spain", "India", "US", "Germany", "Japan", "Canada") print(country[1:4])
            

Output:

('India', 'US', 'Germany')
            

In this example, the slice starts from index 1 (India) and ends before index 4 (Japan), so Japan is not included.  

Slice from the Beginning

If you omit the start index, Python starts the slice from the first item.

Example:

country = ("Spain", "India", "US", "Germany", "Japan", "Canada") print(country[:3])
            

Output:

('Spain', 'India', 'US')
            

Slice to the End

If you omit the end index, Python returns all items from the specified start index to the end of the tuple.

Example:

country = ("Spain", "India", "US", "Germany", "Japan", "Canada") print(country[2:])
            

Output:

('US', 'Germany', 'Japan', 'Canada')
            

Using Negative Indexes

Negative indexes count from the end of the tuple.

Example:

country = ("Spain", "India", "US", "Germany", "Japan", "Canada")
print(country[-4:-1])
            

Output:

('US', 'Germany', 'Japan')
            

Here, -4 refers to "US" and -1 refers to "Canada", which is excluded from the result.  

Using Step Value

Example:

country = ("Spain", "India", "US", "Germany", "Japan", "Canada")

print(country[0:6:2])
            

Output:

('Spain', 'US', 'Japan')
            

The step value 2 returns every second item in the specified range.  

Note: The item at the ending index is always excluded from the sliced result.
