    Creating an API in Python allows applications to communicate over HTTP, enabling data exchange and integration. Two popular frameworks for building APIs are FastAPI and Flask.

    FastAPI Approach

    1. Install Dependencies

    pip install fastapi uvicorn
    Copied!

    2. Create the API File (main.py)

    from fastapi import FastAPI

    app = FastAPI()

    @app.get("/get-message")
    async def read_message(name: str = "User"):
    return {"Message": f"Hello {name}, this is your first API!"}
    Copied!

    3. Run the Server

    uvicorn main:app --reload
    Copied!

    Access at: http://127.0.0.1:8000/get-message?name=John FastAPI automatically generates interactive docs at /docs and /redoc.

    Flask Approach

    1. Install Dependencies

    pip install flask flask-sqlalchemy
    Copied!

    2. Create the API File (app.py)

    from flask import Flask, request, jsonify

    app = Flask(__name__)

    @app.route('/message', methods=['GET'])
    def get_message():
    name = request.args.get('name', 'User')
    return jsonify({"Message": f"Hello {name}, this is your first API!"})

    if __name__ == '__main__':
    app.run(debug=True)
    Copied!

    3. Run the Server

    How do I interface with an API in Python?
    To interface with an API in Python, the requests library is the most popular option. First, you install it via pip install requests.
