My Learning Journey in Backend Development with Python
Introduction
Python is a simple coding language that's easy to read. It's great for web development, data science, and more. In this article, I’ll share what I've learned in backend development with Python.
What It’s About
Python is perfect for backend work. It helps build strong web apps, manage databases, and easily handle server logic. With its many libraries and frameworks, Python makes programming faster.
Core Concepts and Examples
Some key ideas in backend development with Python are frameworks and libraries. Popular ones are Flask, Pyramid, and Django. Let's look at some basics without getting into a specific framework.
Handling HTTP Requests:
Python's requests library helps manage HTTP requests, which is handy for API calls.
import requests
response = requests.get('https://api.example.com/data')
if response.status_code == 200:
data = response.json()
print(data)
Database Management:
Python can work with many databases using libraries like sqlite3. Here’s how to set up a simple database.
import sqlite3
conn = sqlite3.connect('example.db')
c = conn.cursor()
c.execute('''CREATE TABLE IF NOT EXISTS users
(id INTEGER PRIMARY KEY, name TEXT, email TEXT)''')
c.execute(INSERT INTO users (name, email) VALUES ('John Doe', 'john@example.com'))
conn.commit()
conn.close()
Building RESTful APIs:
Creating RESTful APIs is straightforward with Python. Here’s a quick example.
from flask import Flask, jsonify
app = Flask(__name__)
@app.route('/api/v1/users', methods=['GET'])
def get_users():
users = [
{'id': 1, 'name': 'John Doe', 'email': 'john@example.com'},
{'id': 2, 'name': 'Jane Smith', 'email': 'jane@example.com'}
]
return jsonify(users)
if __name__ == '__main__':
app.run(debug=True)
Summary and Key Takeaways
Python is flexible and efficient for web apps. Here’s what I have learnt so far with Python:
Using libraries for HTTP requests and databases is key.
RESTful APIs help connect front and back ends.
Dynamic web apps can be built with templates.
Databases are crucial for data management.
