Loop Tuples

Python – Loop Tuples

Looping through tuples in Python allows you to read and process each element efficiently. Since tuples are ordered and immutable, looping is the primary way to work with their data.
This topic covers all common and practical ways to loop through tuples.

Loop Through a Tuple Using for

The most common and readable approach.
python
fruits = ("apple", "banana", "cherry")

for fruit in fruits:
    print(fruit)
python
numbers = (1, 2, 3, 4)
for num in numbers:
    print(num)

Loop Using Index Numbers

Use this method when you need the index position.
python
colors = ("red", "green", "blue")

for i in range(len(colors)):
    print(colors[i])
python
for i in range(len(colors)):
    print(i, colors[i])

Loop Using while

The while loop provides manual control.
python
numbers = (10, 20, 30)
i = 0

while i < len(numbers):
    print(numbers[i])
    i += 1

Loop Using enumerate()

enumerate() gives index and value together.
python
fruits = ("apple", "banana", "cherry")

for index, value in enumerate(fruits):
    print(index, value)
python
for index, value in enumerate(fruits, start=1):
    print(index, value)

Loop Using Tuple Unpacking

python
pairs = ((1, 2), (3, 4), (5, 6))

for a, b in pairs:
    print(a, b)

Loop Through Nested Tuples

python
matrix = (
    (1, 2),
    (3, 4),
    (5, 6)
)

for row in matrix:
    for value in row:
        print(value)

Loop with Conditions

python
numbers = (10, 15, 20, 25)

for n in numbers:
    if n > 15:
        print(n)

Loop with break

Stops loop execution.
python
numbers = (1, 2, 3, 4, 5)

for n in numbers:
    if n == 3:
        break
    print(n)

Loop with continue

Skips current iteration.
python
numbers = (1, 2, 3, 4, 5)

for n in numbers:
    if n == 3:
        continue
    print(n)

Loop with zip() (Advanced)

Loop through multiple tuples together.
python
names = ("A", "B", "C")
scores = (80, 90, 85)

for name, score in zip(names, scores):
    print(name, score)

Loop Through Tuple in Reverse

python
numbers = (1, 2, 3)
for n in reversed(numbers):
    print(n)

Common Mistakes

Trying to Modify Tuple Inside Loop

python
t = (1, 2, 3)
# t[0] = 10   # TypeError
Tuples cannot be modified.

Performance Note

  • Tuples are faster to iterate than lists
  • Ideal for read-only data
  • Safer for constant data structures

Summary

  • Use for loop for simplicity
  • Use index when position matters
  • enumerate() improves readability
  • Tuple unpacking simplifies nested loops
  • Tuples are read-only during iteration
  • Excellent for fixed and constant data
