The term 'sqlite3' is not recognized

Question

So I am trying to make a flask app login and i did this:

from flask import Flask, render_template, url_for
from flask_sqlalchemy import SQLAlchemy
from flask_login import UserMixin
# from flask_wtf import wtforms
# from wtforms import StringField, PasswordField, SubmitField
# from wtforms.validators import InputRequired, Length,ValidationError

app = Flask(__name__)

app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///database.db'
app.config['SECRET_KEY'] = 'thisisasecreatkey'
db = SQLAlchemy(app)

class User(db.Model, UserMixin):
    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(20), nullable=False, unique=True)
    password = db.Column(db.String(80), nullable=False)

@app.route('/')
def home():
    return render_template('home.html')

@app.route('/login')
def login():
    return render_template('login.html')

@app.route('/register')
def register():
    return render_template('register.html')


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

with app.app_context():
    db.create_all()

and to create a database also did this: from app import app,db

app.app_context().push() db.create_all()

then i got this error: sqlite3 database.db

The term 'sqlite3' is not recognized as a name of a cmdlet, function, script file, or executable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
