Accessing Items

  • This lesson teaches how to access tuple elements using index numbers.

  • Since tuples are ordered, each item has an index number starting from 0.

Access Using Index

Each item in a tuple has a position (index). We use the index number to get the value. 

colors = ("red", "green", "blue", "yellow")

print(colors[0])   # First item
print(colors[2])   # Third item

  • Explanation

    • Index starts from 0

    • colors[0] → red

    • colors[2] → blue

Negative Indexing

Negative indexing starts from the end of the tuple. 

numbers = (10, 20, 30, 40, 50)

print(numbers[-1])
print(numbers[-2])

  • Explanation

    • -1 → last element (50)

    • -2 → second last (40)

Range of Indexes (Slicing)

We can access multiple items using slicing. 

days = ("Mon", "Tue", "Wed", "Thu", "Fri")

print(days[1:4])

  • Explanation

    • Starts from index 1

    • Ends before index 4

    • Output → ('Tue', 'Wed', 'Thu')

Check if Item Exists

We can check whether an item is present using in keyword. 

fruits = ("apple", "banana", "mango")

if "banana" in fruits:
    print("Yes, banana exists")

Loop Through Tuple

We can access all items using loops. 

cars = ("BMW", "Audi", "Tesla")

for car in cars:
    print(car)
