Simple30 second: naam, degree, project kya hai, stack (Flask + Jinja + SQLAlchemy + SQLite).

Example

Main Priya, IITM BS. MAD1 mein parking/ticket app — Flask backend, Jinja templates, session login, SQLite.

SimpleDemo script pehle se practice: 5–7 min, Admin + User roles, saare mandatory features.

Suggested flow1) Register/login user
2) Admin login — CRUD
3) Approval/blacklist
4) Booking/apply + edge case
5) Search
6) Logout

SimpleORM = Object Relational Mapping. Tables → Python classes. Raw SQL kam likhte ho.

Example

class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    email = db.Column(db.String(120), unique=True)

User.query.get(5)  # SELECT ... WHERE id=5

SimplePrimary key row ka unique identity — usually id Integer autoincrement.

Example

id = db.Column(db.Integer, primary_key=True)

SimpleREST: resources + HTTP verbs. GET read, POST create, PUT/PATCH update, DELETE remove. Stateless ideal.

SimpleGET data read/show karta hai (idempotent). POST create/submit karta hai (form).

Example

@app.route('/login', methods=['GET', 'POST'])
def login():
    if request.method == 'POST':
        # validate + session
        ...
    return render_template('login.html')

Simplemodels.py = har table ki class: columns, PK/FK, relationships. Yeh Model layer hai.

Suggested flow1) Classes list karo
2) Har table ka kaam 1 line
3) Relationships (1-M / M-M)
4) Constraints (unique, nullable)

Example

class Lot(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(80), nullable=False)
    spots = db.relationship('Spot', backref='lot', lazy=True)

SimpleList changeable ordered, Tuple fixed ordered, Dict key-value.

list: [1,2,3] — append, mutable, duplicate ok. Arrays jaisa lekin mixed types.
tuple: (1,2) — immutable, dict key ban sakta hai.
dict: {'name':'Ram'} — fast lookup by key. JSON objects dict ban jaate hain.
set: unique items.
Array (JS) ≈ Python list. JS object ≈ Python dict.
Mutable: list, dict. Immutable: tuple, str, int.
