This is very clearly explained in the Flask documentation so I recommend that you read it for a full understanding, but here is a very simple example of rendering template variables.

HTML template file stored in templates/index.html:
```
<html>
<body>
    <p>Here is my variable: {{ variable }}</p>
</body>
</html>
```
And the simple Flask app:
```
from flask import Flask, render_template

app = Flask('testapp')

@app.route('/')
def index():
    return render_template('index.html', variable='12345')

if __name__ == '__main__':
    app.run()
```
Run this script and visit http://127.0.0.1:5000/ in your browser. You should see the value of variable rendered as 12345
