✅ Introduction to Python Data Types

✅In the World-wide Python is one of the most popular programming languages because of its simplicity (easy to use), readability (easy to understand), and flexibility (adaptable to various situations). also Data types in Python tell us the type of value a variable stores, like numbers or text. Learning them helps you manage data better, use it the right way, and avoid common coding errors.


✅Categories of Python Data Types

✔️ 1. Numeric Data Types- In Python Numeric data types represent numbers and allow mathematical operations.

✅ Integers (int)-Integers are whole numbers without a decimal point.



age = 25
year = -2025


✅ Floating-Point Numbers (float)-Floats are numbers with decimals.



price = 19.99
pi = 3.14159


✅ Complex Numbers (complex)-



z = 2 + 3j

💡 Note: Python Data types Data types define the type of value a variable can hold, such as numbers, text, lists, or dictionaries

✅ Types of Data Stored in Python Variables.

✔️ 2. Sequence Data Types - Sequence types store collections of items.

✅ Strings (str)- In Python Data Types Strings represent text, enclosed in single or double quotes.



name = "Python"



✅ Lists (list)- In Python Data Types Lists are ordered, mutable collections.



fruits = ["apple", "banana", "cherry"]



✅ Tuples (tuple)- In Python Data Types Tuples are similar to lists but immutable.



coordinates = (10, 20)



✔️ 3. Set Data Types -In Python Data Types Sets are unordered collections of unique elements.



colors = {"red", "blue", "green"}


✔️ 4. Mapping Data Types -In Python Dictionaries store data as key-value pairs.



student = {"name": "Alice", "age": 20, "grade": "A"}



✔️ 5. Boolean Data Type -In Python Booleans have two values: True or False.



is_active = True



✔️ 6. None Type -



result = None


💡 Note: Python Data types Python is dynamically typed, meaning you don’t need to declare the type of a variable; it’s assigned automatically based on the value.
