In those exercises we use Python 3.10, we then recommend you to install Python 3.10 or higher. + +- [Download and install Python](https://www.python.org/downloads/) + +To write your code, you may use your favorite IDE. If you don't have one, you can go for Visual Studio Code with Python extension pack installed: + +- [Get VS Code](https://code.visualstudio.com/) +- (Optional) [The Python extension pack](https://marketplace.visualstudio.com/items?itemName=donjayamanne.python-extension-pack). + +> Setup may vary in base of your Operating System or machine specificities, if you feel stuck check on internet for the specific steps that suits your configuration. + +### Instructions + +Create a file `hello_python.py` and write inside a function `say_hello_python` that returns the string `"Hello Python!"`. + +```python +def say_hello_python(): + # this is a function, + # write your code here +``` + +### Usage + +Here is a possible code to test your function. Put it in another file (ex: `test.py`): + +```python +from hello_python import say_hello_python + +print(say_hello_python()) +``` + +Run your test file with the following command: + +```console +$ python3 test.py +Hello Python! +$ +``` + +> `test.py` file should be in the same directory of `hello_python.py` in order to work. + +### Hints + +- Python uses indentation to indicate in which block your code will run (many other languages uses parenthesis instead). It is then very important to indent your code properly. + +- `return` is a special world used to say which value a function should return (a function could also not return anything). +For example `return 10` will return the number ten. + +- A string is a set of characters wrapped by `"`. +For example `"Ciao bella"` is a string containing the worlds `Ciao Bella`. + +- In `test.py` we are calling another function named `print`. This function is already present in Python standard library so we don't have to create it. This function at its core is made to write strings in the standard output. + +### References + +- [Indentation in Python](https://www.w3schools.com/python/gloss_python_indentation.asp) +- [Python print function](https://www.w3schools.com/python/ref_func_print.asp)
