Data Types

Data types are the foundation of programming — they define what kind of values a variable can hold and what operations can be performed on them. In Python, understanding data types is essential for:

• Writing correct and efficient code

• Avoiding bugs (e.g., trying to add a string to an integer) and possible crashes

• Optimizing memory and performance

• Critical for certain industries or businesses (Money, Hospitals etc.)

Numeric Types

• int = 10 | Whole Numbers

• float = 13.37 | Decimal Numbers

• str = "hello" | Strings/Text

• complex = "2 + 3j" | Complex Values

---

Boolean

0 False where 1 is True.

• is_active = True (1)

• is_active = False(0)

---

Sequence Types

fruits = ["apple", "banana"]  # list
fruits.append("orange")

coords = (10, 20)             # tuple (can't change)
nums = range(1, 6)            # 1,2,3,4,5

#Lists can be appended, Tupples cannot.
