Iterate over a tuple in Python

Last Updated : 11 Oct, 2024

Python provides several ways to iterate over tuples. The simplest and the most common way to iterate over a tuple is to use a for loop.

Below is an example on how to iterate over a tuple using a for loop.

Python

t = ('red', 'green', 'blue', 'yellow')

# iterates over each element of the tuple 't'
# and prints it
for color in t:
    print(color)

Output

red
green
blue
yellow

Let’s discuss other different methods to iterate through tuples.

Using range() with len()
Using while Loop
Using enumerate() Function

Using range() with len()

Another way to iterate over a tuple is to use the range() along with len(). This method is useful when we need access to the index of each element.

Python

t = ('red', 'green', 'blue', 'yellow')

# Calculate the lenth of a tuple
n = len(t)

# Iterates through the indices from 0 to 3
for i in range(n):
    print(f"Index {i}: {t[i]}")

Output

Index 0: red
Index 1: green
Index 2: blue
Index 3: yellow

Using while Loop

We can also use a while loop to iterate over a tuple. This method is useful when we want more control over the iteration steps.

Python

t = ('red', 'green', 'blue', 'yellow')

# Start from the first index
i = 0

# Loops till the last index (i.e., 3)
while i < len(t):
    print(t[i])
    i += 1

Output

red
green
blue
yellow

Using enumerate()

We can use the enumerate() function of iterate over the tuple, if we need the index along with the value. This function returns both the index and the corresponding value of the tuple.

Python

t = ('red', 'green', 'blue', 'yellow')

# Here, i and color stores the index and value respectively
for i, color in enumerate(t):
    print(f"Index {i}: {color}")

Output

Index 0: red
Index 1: green
Index 2: blue
Index 3: yellow

Iterate over a list in Python

Python provides several ways to iterate over list. The simplest and the most common way to iterate over a list is to use a for loop. This method allows us to access each element in the list directly. Example: Print all elements in the list one by one using for loop. [GFGTABS] Python a = [1, 3, 5, 7,

Tuple Operations in Python

Python Tuple is a collection of objects separated by commas. A tuple is similar to a Python list in terms of indexing, nested objects, and repetition but the main difference between both is Python tuple is immutable, unlike the Python list which is mutable. [GFGTABS] Python # Note : In case of list,

Python - Create a List of Tuples

The task of creating a list of tuples in Python involves combining or transforming multiple data elements into a sequence of tuples within a list. Tuples are immutable, making them useful when storing fixed pairs or groups of values, while lists offer flexibility for dynamic collections. For example

How we can iterate through list of tuples in Python

In Python, a list of tuples is a common data structure used to store paired or grouped data. Iterating through this type of list involves accessing each tuple one by one and sometimes the elements within the tuple. Python provides several efficient and versatile ways to do this. Letâ€™s explore these

Python | Sort Tuples in Increasing Order by any key

Given a tuple, sort the list of tuples in increasing order by any key in tuple. Examples: Input : tuple = [(2, 5), (1, 2), (4, 4), (2, 3)] m = 0 Output : [(1, 2), (2, 3), (2, 5), (4, 4)] Explanation: Sorted using the 0th index key. Input : [(23, 45, 20), (25, 44, 39), (89, 40, 23)] m = 2 Output : So

How to Create an Empty Tuple in Python?

Like an empty list, we can create an empty tuple in Python. Empty tuples can work as a placeholder and are more memory efficient compared to empty lists because tuples are immutable.
