Hi Roman Kovalchik,

Your code is correct but it almost follows all the PEP 8 conventions.

There’s just one small style issue: you used three blank lines between your app variable and the route definition. PEP 8 recommends using two blank lines between top-level sections (like functions or decorators).

Here's how it should look:

...
app = Flask(__name__)


@app.route('/')
def index():
    return 'Hello Flask'
...

Functionally, your code is excellent — this is just about keeping it clean and consistent. Keep up the great work! 🚀
