Day-2 - Python Data Types – A Beginner’s Guide

When we start learning Python, one of the most important concepts to understand is data types.

Data types tell Python what kind of value a variable is storing — whether it’s text, a number, or a logical value.

The 4 Primitive Data Types in Python

Python provides four commonly used (primitive) data types:

1. String (str)

• Represents a sequence of characters (text).

• Example:

name = "Ravi"
message = "Hello, Python!"

---

2. Integer (int)

• Represents whole numbers, both positive and negative.

• Example:

age = 30
year = -2025

---

3. Float (float)

• Represents numbers with decimal points.

• Example:

pi = 3.14
temperature = -5.8

---

4. Boolean (bool)

• Represents logical values, either True or False.

• Example:

is_active = True
is_admin = False

Dynamic Typing in Python

Unlike many other programming languages, Python does not require you to explicitly declare the type of a variable.

Instead, Python uses dynamic typing, which means it automatically detects the type based on the value you assign.

✅ Example:

username = "Alice"     # String
score = 95             # Integer
height = 5.9           # Float
is_verified = True     # Boolean

Here, Python figures out the data type for each variable on its own.

Final Thoughts

Python’s dynamic typing makes it beginner-friendly and flexible. You don’t need to worry about declaring data types — just assign a value, and Python will handle the rest. 🚀
