<h2 id="configuring-your-project-for-the-application">Configuring your project for the application</h2>
<p>You will need to associate the code to a project if not
already done. If you don't have a project, just opening the folder
with PyCharm should suffice.</p>
<p>However, you need to have a <code>virtualenv</code> for your project (for good
practice), that uses Python 3.6+.</p>
<p>In this virtualenv, you'll have to install :</p>
<ul>
<li><code>pyside6</code></li>
</ul>
<p>Note that Qt has issues with theming; if PySide6 is installed, using <code>pip</code> or
another medium, it won't follow the system theme. However, if PySide2 is
installed globally on the system (via <code>apt-get</code> or <code>pacman</code>), programs seem to
follow the system theme. One would then have to revert to importing from
<code>PySide2</code> instead of <code>PySide6</code> (with no other changes).</p>
<h2 id="how-to-run-the-application">How to run the application</h2>
<p>The application is very simple to run in PyCharm.
To do it, right-click on the source file content pane, somewhere where
there is an empty space.</p>
<p>Then, click the <code>Run &lt;application&gt;...</code>.</p>

## Configuring your project for the application
You will need to associate the code to a project if not
already done. If you don't have a project, just opening the folder
with PyCharm should suffice.
However, you need to have a `virtualenv` for your project (for good
practice), that uses Python 3.6+.
In this virtualenv, you'll have to install :
- `pyside6`
Note that Qt has issues with theming; if PySide6 is installed, using `pip` or
another medium, it won't follow the system theme. However, if PySide2 is
installed globally on the system (via `apt-get` or `pacman`), programs seem to
follow the system theme. One would then have to revert to importing from
`PySide2` instead of `PySide6` (with no other changes).
## How to run the application
The application is very simple to run in PyCharm.
To do it, right-click on the source file content pane, somewhere where
there is an empty space.
Then, click the `Run <application>...`.

= Exercices sur la fonction `print()`
== Exercice 1
Affichez dans la console le texte suivant :
- La rue Rostand,
- `3 espaces` se trouve au
- Feu à droite
== Exercice 2
La fonction `print()` accepte plusieurs arguments, dont les valeurs sont affichées sur la même ligne, et par défaut séparés par un espace.
*La syntaxe est la suivante* : `print("a", "b", "c", 19)`
Affichez, en imitant cette syntaxe, le texte suivant :
* Hauts les cœurs !
(sous Linux, le e dans l'o s'obtient avec la combinaison de touches `Alt Gr + O`. Sous Windows, `Alt + 339` devrait donner le même résultat)
== Exercice A1
La fonction `print()` accepte des arguments avec des noms spécifiques, dont `sep` et `end`. `sep` permet de désigner quelle chaîne sépare les arguments à afficher, et `end` permet de préciser par quelle chaîne terminer le `print`.
Par défaut, `sep=" "` et `end="\n"`. La fonction s'utiliserait ainsi :
```python
# Ne sépare pas les éléments via un espace et passe deux fois
# à la ligne à la fin du print.
print("1", "2", "3", sep="", end="\n\n")
```

= Variables
---
== Exercice 1
- Déclarez trois variables, avec des noms corrects, contenant :
* Le nom d'une personne, ex. "Paul"
* La température courante en °C, ex. 25.3
* L'âge d'une personne, ex. 30
- Affichez dans la console les valeurs de ces trois variables.
---
== Exercice 2
- Demandez à l'utilisateur de saisir du texte, et mettez-le dans une variable
- Affichez le contenu de la variable.
*Fonctions nécessaires* : `variable = input("Texte d'invite:")`, `print()`
---
== Exercice 3 : Expressions
- Déclarez plusieurs variables, contenant le résultats de :
* Une opération arithmétique entre nombres
* Une comparaison entre nombres
* Une opération d'addition entre deux chaînes
* L'expression `(59 * 62 + 13) / 6.5`
- Affichez leur contenu dans la console.
---
== Exercice A1 : Conversion en ordres de grandeur
- Déclarez une variable contenant une distance en mètres (au moins 1001, ex 4210)
- Affichez le nombre de kilomètres dans cette valeur (nombre entier, ex. 4)
- Afficher le nombre de mètres restants dans cette valeur (ex. 210)
*Outils nécessaires* : opérateurs `//` (division entière), `%` (modulo)
Vous pouvez afficher tout cela sur une ligne avec un seul appel à la fonction `print()`, par exemple :
```python
kilometers = 5
meters = 450
print(kilometers, "kilomètres et", meters, "mètres.")
```
---
== Exercice A2 : Deux ordres de grandeur
- Déclarez une variable contenant une masse en grammes (au moins 1 000 000)
- Affichez le nombre de tonnes, de kilogrammes et de grammes dans cette masse.
Vous devrez utiliser les mêmes outils que dans l'exercice précédent, mais il
y a deux ordres de grandeur à prendre en compte !
---
== Exercice A3 : Saisie de nombres
- Demandez à l'utilisateur de saisir deux nombres (en deux fois).
- Indiquez quel est le nombre le plus grand qui a été saisi.
Sachant que la saisie récupérée est toujours une chaîne de caractères vous devez récupérer une version de la saisie qui est un nombre pour pouvoir faire des comparaisons intéressantes.
*Rappel* : pour récupérer un entier depuis une chaîne, utilisez `int(valeur)`

= Conditions
---
== Exercice 1 : `if` seul

- Affichez `"Lancer réussi !"` si la valeur est supérieure strictement à 4
- Retestez votre code en changeant la valeur du lancer
---
== Exercice 2 : `if` seul, comparer du texte
- Déclarez une variable avec le texte `"Bonjour"`;
- Affichez `"Bien le bonjour"` si votre variable est égale à `"bonjouR"`.
(Les majuscules ne sont pas placées ici par hasard, conservez-les)
---
== Exercice 2B : `if…else`
- Assignez à une variable le texte `"Bonjour"`;
- Affichez `"Bien le bonjour"` si votre variable est égale à `"Bonjour"`;
- Sinon, (dans tous les autres cas) afficher `"Je ne comprends pas !"`.
---
== Exercice 3 : `if…elif…else`
- Assignez à une variable un entier arbitraire entre 0 et 10 inclus;
- Si cette valeur est d'au moins 9, afficher `"Élevé"`;
- Sinon, si cette valeur est d'au moins 7, afficher `"Haut"`;
- Sinon, si cette valeur est d'au moins 4, afficher `"Standard"`;
- Sinon, afficher `"Bas"`.
---
== Exercice A1 : Multiples conditions
- Assignez à deux variables `a1` et `a2` des nombres entiers entre 0 et 10
- Si `a1` est supérieur à 5 *et* `a2` est inférieur à 6, afficher `"OK"`
- Sinon, afficher `"Valeurs incorrectes"`
---
== Exercice A2 (conditions avec `and` et `or`)
- Assignez à deux variables `a1` *et* `a2` des nombres entre 0 et 10
- Si `a1` est supérieur à 5 *ou* `a2` est inférieur à 6, afficher `"Conditions suffisantes"`
- Sinon, afficher `"Valeurs incorrectes"`
---
== Exercice A3
- Déclarez une variable de statut `is_on` contenant un booléen (`True` ou `False`)
- Demandez à l'utilisateur de *saisir un texte*, et assignez-le à une variable `saisie`
- Si `saisie` vaut "Marche" :
* Si `is_on` est `False`, alors afficher "Allumage en cours..."
* Sinon, afficher "Déjà allumé !"
- Sinon, si `saisie` vaut "Arrêt" :
* Si `is_on` est `True`, afficher "Extinction..."
* Sinon, afficher "Déjà éteint !"
Exemple de rappel :
```python
# Demander de saisir un texte et récupérer le résultat dans une variable
saisie = input("Saisissez du texte :")
```
