CREATING DATABASE FILE IN FLASK

I'm a newbie in Python and Flask so I was following a tutorial on youtube https://youtu.be/2geC50roans?t=362. All was well until the point I needed to create a database file. My code didn't create a file as in the tutorial, however I'm not seeing where my code differs with that on the tutorial. I'm using python 3.8 and Pycharm on windows 10. I have also installed Flask, SQLite3, flask_sqlalchemy, sqlalchemy as required by the tutorial. My code is as follows;

from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from sqlalchemy import Column, Integer, Text

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///pin.db'
db = SQLAlchemy(app)


class Pin(db.Model):
    id = Column(Integer, primary_key=True)
    title = Column(Text, unique=False)
    image = Column(Text, unique=False)


db.create_all()


@app.route('/')
def index():
    return "Hello World!"


app.debug = True

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

The following is the error message:
