Variable
Variable
A variable is a container that stores data. For example, name = "Alice" creates a variable named name that holds the value "Alice".
Data Type
Data Type
A data type defines the kind of values a variable can hold. Common data types include integers (int), floating-point numbers (float), strings (str), and booleans (bool).
Arithmetic Operators
Arithmetic Operators
Operators are symbols that perform specific actions on data. Arithmetic operators include addition (+), subtraction (-), multiplication (*), division (/), and modulus (%).

Study Notes
Python Programming Fundamentals
- Python is an easy-to-learn, powerful programming language used for web development, data analysis, AI, and automation.
- Install Python from python.org and an IDE (like Visual Studio Code or Jupyter Notebook)
Python Variables and Data Types
- Variables store data (e.g.,
x = 5,name = "Alice"). - Data types include:
int(integers, e.g., 10)float(decimal numbers, e.g., 3.14)str(strings, e.g., "Hello")bool(Boolean values, True or False)
Python Operators
- Arithmetic:
+(addition)-(subtraction)*(multiplication)/(division)%(modulus)
- Comparison:
==(equal to)!=(not equal to)>(greater than)<(less than)>=(greater than or equal to)<=(less than or equal to)
- Logical:
andornot
Control Flow (if-else, loops)
- if-else statements control the flow based on conditions (e.g., if age >= 18: print("Adult")).
- Loops:
forloops iterate over a sequence (e.g.,for i in range(5): print(i)).whileloops execute as long as a condition holds true (e.g.,count = 0; while count < 5: print(count); count += 1).
Python Functions
- Define functions using
def(e.g.,def greet(name): ...) for modular code. - Functions can take parameters (inputs) and return values.
Python Lists
- Lists are ordered collections of items.
- Example:
fruits = ["apple", "banana", "cherry"] - Access items by index (
fruits[1] = banana). - Iterate through lists using a
forloop
- Example:
Python Dictionaries
- Dictionaries store key-value pairs.
- Example:
student = {"name": "Alice", "age":20} - Access values by key (
student["name"]).
- Example:
Python File Handling
- Read from and write to files using the
with open(...)statement (e.g., open a file in read mode, write something to it and close it).
Python Object-Oriented Programming (OOP)
- Create classes and objects to structure code.
- Example:
class Person:...Â
Python Practice Programs (Examples)
- Simple Calculator:
- Takes two numbers and an operation as input.
- Calculates results using the specified operator
- FizzBuzz:
- Iterates through the numbers 1-100 and prints "Fizz", "Buzz", or "FizzBuzz" according to divisibility rules.
