Product Management System Using Python project in Python.

? Step-by-Step: How to Import and Run a Python Flask Project

? 1. Install Prerequisites

Make sure you have:

• Python 3.x installed ? check with:

python --version

• pip (Python package manager) ? check with:

pip --version

________________________________________

? 2. Download or Clone the Project

If it's in a .zip file:

• Extract it to your desired folder.

If it's on GitHub:

git clone https://github.com/yourusername/yourproject.git

cd yourproject

________________________________________

? 3. Create and Activate a Virtual Environment (Recommended)

python -m venv venv

Activate it:

• Windows:

venv\Scripts\activate

• Mac/Linux:

source venv/bin/activate

________________________________________

? 4. Install Required Libraries

Make sure you have a requirements.txt file. Then run:

pip install -r requirements.txt

If you don’t have requirements.txt, install manually:

pip install flask

(add more like flask_sqlalchemy, flask_login etc., based on your project)

________________________________________

?? 5. Configure the Project

Check if there's a .env file or config.py with variables like:

• FLASK_APP=app.py

• FLASK_ENV=development

If not, set it manually:

set FLASK_APP=app.py # Windows

export FLASK_APP=app.py # Mac/Linux

? If You’re Using SQLite:

1. Create the SQLite File

You can either:

Let Flask create it programmatically using SQLAlchemy

Or manually create a file like product.db and tables using a tool (like DB Browser for SQLite)

2. Add DB Connection in Flask

from flask import Flask

import sqlite3

app = Flask(__name__)

DATABASE = 'product.db'

def get_db_connection():

conn = sqlite3.connect(DATABASE)

conn.row_factory = sqlite3.Row

return conn

3. Initialize Tables

You can create a schema.sql file with your table definitions:

CREATE TABLE products (

id INTEGER PRIMARY KEY AUTOINCREMENT,

name TEXT NOT NULL,

category TEXT,

stock INTEGER,

price REAL

);

Then run this from a setup script or Flask CLI:

def init_db():

with app.app_context():

db = get_db_connection()

with open('schema.sql') as f:

db.executescript(f.read())

db.commit()

Call init_db() once to create tables.
