📗 Episode 3: Understanding Tuples in Python – DarchumsTech Series

Welcome to Episode 3 of the Data Structures in Python series. Today we’re diving into Tuples, a simple but powerful structure used for storing collections of data.

---

📦 What is a Tuple?

A Tuple is an ordered and immutable collection of items. Once a tuple is created, you cannot change its contents. Tuples use parentheses () instead of square brackets.

---

🛠 Creating and Accessing Tuples

You can define a tuple using parentheses. Items are accessed by index, just like lists.

person = ("John", 30, "USA")
print(person[0])   # John
print(person[-1])  # USA

---

🎯 Why Use Tuples?

• Immutable: Protects data from accidental changes
• Faster: Performance advantage over lists
• Used as keys: Can be dictionary keys (lists cannot)
• Memory efficient: Smaller memory footprint

---

🔄 Tuple Unpacking

You can assign each element in a tuple to a variable in a single line.

name, age, country = person
print(name)     # John
print(age)      # 30
print(country)  # USA

---

⚠️ Tuple Immutability

Trying to modify a tuple will raise an error:

person[0] = "Jane"  # ❌ This will cause a TypeError

📌 Summary

• Tuples are ordered and immutable.
• Ideal for fixed data collections like coordinates, RGB values, or config data.
• Support indexing, slicing, and unpacking.
