1. Hello World Program
print("Hello, World!")The quintessential beginner's program in Python, it simply prints "Hello, World!" to the console.
2. Calculator Program
def add(x, y): return x + y def subtract(x, y): return x - y def multiply(x, y): return x * y def divide(x, y): return x / yThis program defines basic arithmetic operations such as addition, subtraction, multiplication, and division.
3. Fibonacci Series Program
def fibonacci(n): fib_series = [0, 1] for i in range(2, n): fib_series.append(fib_series[i-1] + fib_series[i-2]) return fib_seriesGenerates the Fibonacci series up to the specified number of terms 'n'.
4. Guessing Game Program
import random def guessing_game(): number = random.randint(1, 100) guess = int(input("Guess the number (between 1 and 100): ")) while guess != number: if guess number: print("Too low. Try again.") else: print("Too high. Try again.") guess = int(input("Guess again: ")) print("Congratulations! You guessed the correct number.") guessing_game()Interactive game where the user guesses a randomly generated number.
5. File Handling Program
# Writing to a file with open('example.txt', 'w') as file: file.write("This is an example text.") # Reading from a file with open('example.txt', 'r') as file: content = file.read() print(content)Demonstrates writing and reading text to and from a file.
6. Web Scraping Program
import requests from bs4 import BeautifulSoup url = 'https://www.example.com' response = requests.get(url) soup = BeautifulSoup(response.text, 'html.parser') print(soup.title)Scrapes the title of a webpage using BeautifulSoup.
7. Basic GUI Program
import tkinter as tk root = tk.Tk() root.title("Simple GUI") label = tk.Label(root, text="Hello, GUI!") label.pack() root.mainloop()Creates a simple graphical user interface with a greeting message.
8. Data Visualization Program
import matplotlib.pyplot as plt x = [1, 2, 3, 4, 5] y = [2, 3, 5, 7, 11] plt.plot(x, y) plt.xlabel('X-axis') plt.ylabel('Y-axis') plt.title('Simple Line Plot') plt.show()Plots a simple line graph using Matplotlib.
9. Sending Email Program
import smtplib from email.mime.text import MIMEText def send_email(): sender_email = 'your_email@gmail.com' receiver_email = 'recipient_email@gmail.com' message = MIMEText('This is a test email.') message['Subject'] = 'Test Email' message['From'] = sender_email message['To'] = receiver_email with smtplib.SMTP('smtp.gmail.com', 587) as server: server.starttls() server.login(sender_email, 'your_password') server.sendmail(sender_email, receiver_email, message.as_string()) send_email()Sends a test email using the SMTP protocol.
10. Database Connectivity Program
import sqlite3 # Connect to SQLite database conn = sqlite3.connect('example.db') # Create a cursor object cursor = conn.cursor() # Execute SQL query cursor.execute('''CREATE TABLE IF NOT EXISTS students (id INTEGER PRIMARY KEY, name TEXT, age INTEGER)''') # Insert data into the table cursor.execute("INSERT INTO students (name, age) VALUES ('John', 25)") # Commit changes and close connection conn.commit() conn.close()Demonstrates basic database connectivity and CRUD operations with SQLite.
