# Flask


## Introduction
Flask is a micro web framework written in Python. It is easy to use and has a lot of documentation. We are going to use Flask to serve our REST api.

## Cheatsheet
```python
print(f"Hello world have a nice {args}!")
```
This way you can put variables in a string. This is called f-strings.



## Rules for python
* You can only use one return statement in a function.
