Day 1: Introduction to Python

Description:
Python is a versatile, high-level, and interpreted programming language known for its simplicity and readability. It’s widely used for web development, data analysis, machine learning, and more.

Key Terms:

Interpreter: Executes Python code line by line.
Script: A file containing Python code.
Variables: Containers for storing data.

# Simple Python script
print(“Welcome to Python!”)

# A basic Python script to demonstrate variables and printing
name = “Alice”
age = 25
print(f”My name is {name} and I am {age} years old.”)

Day 2: Python Variables and Data Types

Description:
Python variables are used to store data, and data types define the type of the value stored in a variable. Python supports data types like integers, floats, strings, and booleans.

        # Syntax to define variables

        variable_name = value

        # Examples of different data types

        x = 10         # Integer

        y = 3.14       # Float

        name = “Python” # String

        is_python_fun = True  # Boolean

        # Printing variables

        print(x, y, name, is_python_fun)

Day 3: Basic Input and Output

Description:
Python uses the input() function to accept user input and print() to display output.

        # Taking input

        variable = input(“Enter something: “)

        # Displaying output

        print(“You entered:”, variable)

        # Input and output example

        name = input(“What’s your name? “)

        print(f”Hello, {name}!”)

Day 4: Python Operators

Description:
Operators are used to perform operations on variables and values. Python supports arithmetic (+, -, *, /), logical (and, or, not), and comparison (<, >, ==) operators.

        # Arithmetic operators

        a = 10

        b = 3

        print(“Sum:”, a + b)

        print(“Division:”, a / b)

        # Logical operators

        print(“True and False:”, True and False)

Day 5: Conditional Statements

Description:
Conditional statements let you execute code blocks based on specific conditions.

        # Conditional statements

        age = int(input(“Enter your age: “))

        if age < 18:

            print(“You are a minor.”)

        elif age == 18:

            print(“You just became an adult!”)

        else:

            print(“You are an adult.”)

Day 6: Loops

Description:
Loops (for and while) allow you to repeat a block of code multiple times.

# For loop example
for i in range(5):
    print(f”Iteration {i}”)

# While loop example
count = 0
while count < 5:
    print(f"Count: {count}")
    count += 1

Day 7: Lists

Description:
Lists are used to store multiple items in a single variable. They are mutable, ordered, and allow duplicate elements.

# List operations
fruits = [“apple”, “banana”, “cherry”]
fruits.append(“orange”)
fruits.remove(“banana”)
print(fruits)

Day 8: Tuples and Dictionaries

Description:
Tuples are immutable collections, while dictionaries store key-value pairs.

# Tuple example
colors = (“red”, “green”, “blue”)
print(colors[0])

# Dictionary example
person = {“name”: “Alice”, “age”: 25}
print(person[“name”])

Day 9: Functions

Description:
Functions are reusable blocks of code designed to perform a specific task.

# Function example
def greet(name):
    return f”Hello, {name}!”

print(greet(“Alice”))
