I run this application but it is not connecting to MySQL database. I am using Python version 3.7.4 and Flask-SQLAlchemy version 2.4.1
from flask import Flask , render_template, request
from flask_sqlalchemy import SQLAlchemy
app = Flask(__name__)       
app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False
app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql://root:@localhost/codingthunder'
db = SQLAlchemy(app)
class Contacts(db.Model):               **# Table in database = contacts**
    sno = db.Column(db.Integer , primary_key=True)   **# sno = Primary key** 
    name = db.Column(db.String(80),unique=False, nullable=False)
    def __repr__(self):
        return f"<User> {self.name}"
@app.route("/")             #defining route
def home():
    return render_template("/index.html")
@app.route("/contact" , methods = ['GET','POST'])     
def contact():
    if request.method == 'POST':
        entry = Contacts(name = "ashfaq")
        db.session.add(entry)
        db.session.commit()
    return render_template("contact.html")        
app.run(debug = True)           
And the Error is ModuleNotFoundError: No module named 'MySQLdb'
