Python

Because random in numpy, isn't it?

Why would you use something as massive as numpy for a thing that the standard library can do https://docs.python.org/3/library/random.html

OK OK I mistake the random module

No, and it is not needed, code and output is text

Hello Greetings to you. may peace, mercy and blessings of almighty be upon you. how are you doing guys

All.. I have been searching on Google an "easy to use" python ide.. and I did download a few and tried using.. but did not find simple and so removed.. any here can suggest me a simple and easy IDE

In my opinion, it would be more efficient to go ahead and install VSCode or PyCharm. But if you insist try online-python.com.

You can download tonny IDE. It's simple and easy to download

Someone shared me this code pls explain : from flask import Flask, render_template, request, redirect, url_for, flash, session, abort from flask_sqlalchemy import SQLAlchemy from flask_wtf import FlaskForm from wtforms import StringField, PasswordField, TextAreaField, SubmitField from wtforms.validators import DataRequired, Length from passlib.hash import bcrypt from datetime import datetime app = Flask(name) app.config['SECRET_KEY'] = 'replace-this-with-a-secure-random-string' app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///progsite.db' app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False db = SQLAlchemy(app) # ---------- Models ---------- class User(db.Model): id = db.Column(db.Integer, primary_key=True) username = db.Column(db.String(80), unique=True, nullable=False) password_hash = db.Column(db.String(255), nullable=False) is_admin = db.Column(db.Boolean, default=False) def verify_password(self, password): return bcrypt.verify(password, self.password_hash) class Problem(db.Model): id = db.Column(db.Integer, primary_key=True) title = db.Column(db.String(200), nullable=False) statement = db.Column(db.Text, nullable=False) sample_input = db.Column(db.Text, default='') sample_output = db.Column(db.Text, default='') created_at = db.Column(db.DateTime, default=datetime.utcnow) class Submission(db.Model): id = db.Column(db.Integer, primary_key=True) user_id = db.Column(db.Integer, db.ForeignKey('user.id')) problem_id = db.Column(db.Integer, db.ForeignKey('problem.id')) code = db.Column(db.Text, nullable=False) verdict = db.Column(db.String(50), default='Pending') created_at = db.Column(db.DateTime, default=datetime.utcnow) user = db.relationship('User', backref='submissions') problem = db.relationship('Problem', backref='submissions') # ---------- Forms ---------- class RegisterForm(FlaskForm): username = StringField('Username', validators=[DataRequired(), Length(min=3, m

You may want to start reading flask documentation Is not effective to just ask to explain a full program better to be more specific

I don't have idea how to do that?

For a web crawler project, which library is the best to use? Currently, I'm a beginner and it's hard for me to write the program independently without following the books. I'm currently using requests and BeautifulSoup. I'm worried that my learning method might be wrong, so I'm here to ask for advice.

nothing wrong, with a web crawler project you will sharpen your algorithmics thinking and when you dive deeper you might learn how internet/http/web works, control flow with concurrency/parallelism, and many more. its always better in programming if you have/know- reason for using tools/library when you decided to use it, because thats a signal that you know what you're doing. so, which library is the best? it depends on problem you want to solve

You mention Django and then say that you have no idea ? 🤔 Why pick Django then ? If you know why read through the Django documentation and quick tutorial to work on implementation.

Do you know the GitHub website?

Of course but remember this group is to talk about python only

Oh okay, I'm just asking, we're still in contact a little bit, right?

What I meant is: there are places to talk about that or other casual stuff check offtopic group (link in the rules)
