To run my Python OpenAI App in a browser I am going with <code>Flask</code>, which is apparently simpler than <code>Django</code> and other similar frameworks.
Below I documented how to get to an easy ‘hello world’, which is the starting point for everything else I do with <code>Flask</code> after that.

To run my Python OpenAI App in a browser I am going with `Flask`, which is apparently simpler than `Django` and other similar frameworks.

Below I documented how to get to an easy ‘hello world’, which is the starting point for everything else I do with `Flask` after that.

# 1\. Install Flask

Terminal: `pip install Flask`

# 2\. **Create the Flask App**

Create a new Python file [`app.py`](http://app.py) and write the following code:

```python
from flask import Flask

app = Flask(__name__)

@app.route('/')
def hello_world():
    return 'Hello, World!'

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

# 3\. Run the Flask App

Terminal: `python` [`app.py`](http://app.py)
