Python, as a highly concise and expressive programming language, allows developers to create powerful programs in a surprisingly small number of lines. In this blog post, we’ll explore the potential of Python by creating mini-programs using just 30 lines of code.
1. Simple Web Server
With the help of the http.server module in Python’s standard library, you can set up a basic web server in just a few lines. Here’s an example:
pythonimport http.server
import socketserver
PORT = 8000
Handler = http.server.SimpleHTTPRequestHandler
with socketserver.TCPServer(("", PORT), Handler) as httpd:
print("Serving at port", PORT)
httpd.serve_forever()
2. Fibonacci Sequence Generator
A Fibonacci sequence is a series of numbers where each number is the sum of the two preceding numbers. Here’s a short program that generates the first 10 Fibonacci numbers:
pythondef fibonacci(n):
a, b = 0, 1
for _ in range(n):
yield a
a, b = b, a + b
for num in fibonacci(10):
print(num)
3. Password Generator
A simple password generator can be created using Python’s random module:
pythonimport random
import string
def generate_password(length=10):
characters = string.ascii_letters + string.digits + string.punctuation
return ''.join(random.choice(characters) for i in range(length))
print(generate_password(10))
4. Text File Reader
A program to read the contents of a text file can be written in just a few lines:
pythonwith open('example.txt', 'r') as file:
content = file.read()
print(content)
5. Temperature Converter
A simple program to convert Fahrenheit to Celsius:
pythondef fahrenheit_to_celsius(fahrenheit):
return (fahrenheit - 32) * 5 / 9
fahrenheit = float(input("Enter temperature in Fahrenheit: "))
celsius = fahrenheit_to_celsius(fahrenheit)
print(f"{fahrenheit}°F is equal to {celsius}°C")
Each of these programs demonstrates the power and conciseness of Python. While they are simple, they highlight the potential of writing efficient and effective programs in a small number of lines.
