Using TUPLES in Python

Continuing my posts about Python collections (see post about sets), let's look at another important data structure in Python - the tuple.

So when is it used and how does it differ from a list?

🌟 Strengths of Tuples:
- Immutable: Once created, they cannot be modified. This makes them hashable and usable as keys in dictionaries.
- Memory Efficient: Tuples are generally more memory-efficient than lists.
- Safety: Since they are immutable, there’s no risk of unintended side-effects when passing them around in functions.

🚫 Weaknesses of Tuples:
- Limited Flexibility: You can't add, remove, or modify elements after creation.
- Fewer Methods: They come with fewer built-in methods compared to lists.

πŸ” When to use Tuples:
- When you need a collection of data that shouldn't change, like the days of the week or coordinates of a point.
- When you want to ensure data integrity and prevent accidental modifications.
- As keys for dictionaries.

✨ Differences from Lists:
- Mutability: Lists are mutable, tuples are not.
- Syntax: Lists use square brackets [] and tuples use parentheses ().
- Methods: Lists have several methods like append(), remove(), and extend(), which tuples do not (given their immutable nature).

# Creating a Tuple
container_size = (5.0, 10.0)

# Accessing Elements
print(container_size[0])  # Outputs: 5.0

# Tuples in Dictionaries
locations = {(40.7128, -74.0060): 'New York', (51.5008, -0.1177): 'London'}

# List vs Tuple
example_list = [1, 2, 3]
example_type = (1, 2, 3)
example_list[1] = 4  # Valid
# my_tuple[1] = 4  # Throws an error

Tuples are great in their domain of applications! But like every tool, they have their place. Know when to use them over lists and leverage their strengths.

Happy coding! πŸš€
