📌 Extra: Python Data Types & Code Example
Python is dynamically typed — you don’t need to declare the type.

Common Types:

• int – 42

• float – 3.14

• str – "Hello"

• bool – True / False

Example Code:

age = 25          # int
price = 19.99     # float
name = "Alice"    # str
is_happy = True   # bool

print(name, "is", age, "years old.")
