Il ne s'exécute que si le `for` sort sans `break`.
|
||||
|
||||
|
||||
## `else`
|
||||
|
||||
```python
|
||||
n = 13
|
||||
for i in range(2, n - 1):
|
||||
if n % i == 0:
|
||||
print(f"{n} is not prime")
|
||||
break
|
||||
else:
|
||||
print(f"{n} is prime")
|
||||
```
|
||||
|
||||
Notes:
|
||||
|
||||
Typiquement utile lors des recherches, la sémantique :
|
||||
- Trouvé, plus besoin de chercher, break.
|
||||
- else: pas trouvé.
|
||||
|
||||
Fonctionne aussi sur le while.
|
||||
|
||||
Ah j'ai utilisé une f-string.
|
||||
|
||||
|
||||
## Literal String Interpolation
|
||||
|
||||
```python
|
||||
>>> f"{42:08b}"
|
||||
00101010
|
||||
```
|
||||
|
||||
Notes:
|
||||
|
||||
Attention aux ':' et '!' dans l'expression, bien que ce soit accepté
|
||||
si c'est entre guillemet, crochets, parenthèses, ... sinon toute
|
||||
expression Python est autorisée (comme avec .format, mais avec .format
|
||||
c'est plus évident).
|
||||
|
||||
|
||||
## Literal String Interpolation
|
||||
|
||||
```python
|
||||
>>> f"{(lambda x: x.upper())('hello'):^11}"
|
||||
' HELLO '
|
||||
```
|
||||
|
||||
Notes:
|
||||
|
||||
Attention à rester lisible, mais ici le `:` de la lambda est entre
|
||||
parenthèses, donc c'est bon.
|
||||
|
||||
En parlant de parenthèse, fermons une parenthèse.
|
||||
|
||||
|
||||
## On parlais d'itérables
|
||||
|
||||
Si on parlais d'unpacking ?
|
||||
|
||||
Notes:
|
||||
|
||||
Pour se remémorer ces choses, cherchez les PEPs, typiquement la 448, la 3132, ...
|
||||
|
||||
Parler de `deep unpacking`.

||||

# Les objets
|
||||
|
||||
## Rappels
|
||||
|
||||
- Keep it simple.
|
||||
- Flat is better than nested.
|
||||
|
||||
|
||||
## `classmethod` vs `staticmethod`
|
||||
|
||||
## La MRO
|
||||
|
||||
## `super()` !
|
||||
|
||||
Notes:
|
||||
|
||||
Et la coopération.
|
||||
|
||||
|
||||
## Le protocole « descripteur »
|
||||
|
||||
- `object.__get__(self, instance, owner=None)`
|
||||
- `object.__set__(self, instance, value)`
|
||||
|
||||
Notes:
|
||||
|
||||
Et `__delete__` et `__setname__`.
|
||||
|
||||
- instance... c'est l'instance.
|
||||
- owner, c'est le type, il est toujours connu donc "devrait" toujours être donné
|
||||
- Si instance n'est pas donnée, c'est qu'on accède à l'attribut sur le type.
|
||||
|
||||
|
||||
## Métaclasses
|
||||
|
||||
Puisqu'une classe est un objet, une métaclasse c'est le type du type.
|
||||
|
||||
Notes:
|
||||
|
||||
En initiation on dit "ça ne vous servira pas". En avancé on dit
|
||||
`__init_subclass__` couvrira tous vos besoins.
|
||||
|
||||
|
||||
## Métaclasse
|
||||
|
||||
- `__new__` et `__init__` d'une classe servent à personaliser l'instance.
|
||||
- `__new__` et `__init__` d'une metaclasse servent à personalier une classe.
|
||||
|
||||
Notes:
|
||||
|
||||
```python
|
||||
class M(type):
|
||||
def __new__(cls, *args, **kwargs):
|
||||
print(f"meta.__new__(*{args}, **{kwargs})")
|
||||
return super().__new__(cls, *args, **kwargs)
|
||||
|
||||
def __init__(self, *args, **kwargs):
|
||||
print(f"meta.__init__(*{args}, **{kwargs})")
|
||||
super().__init__(*args, **kwargs)
|
||||
|
||||
class MyCls(metaclass=M):
|
||||
def __new__(cls, *args, **kwargs):
|
||||
print(f"cls.__new__(*{args}, **{kwargs})")
|
||||
return super().__new__(cls, *args, **kwargs)
|
||||
|
||||
def __init__(self, *args, **kwargs):
|
||||
print(f"cls.__init__(*{args}, **{kwargs})")
|
||||
super().__init__(*args, **kwargs)
|
||||
```

# Langage
|
||||
|
||||
## `id` et `is`
|
||||
|
||||
Notes:
|
||||
|
||||
- `is` pour les singletsons `None`, `True`, `False`.
|
||||
- `id` : identifiant unique, l'adresse mémoire en CPython.
|
||||
- `is` sémantiquement est donc `id(left) == id(right)` mais attention au GC.
|
||||
|
||||
|
||||
## Parenthèse sur les singletons
|
||||
|
||||
Notes:
|
||||
|
||||
Un module est un singleton.
|
||||
|
||||
|
||||
## String interning
|
||||
|
||||
```python3
|
||||
a = "Bonjour !"
|
||||
b = "Bonjour !"
|
||||
a is b
|
||||
```
|
||||
|
||||
?
|
||||
|
||||
Notes:
|
||||
|
||||
- C'est dépendant de l'implémentation, ça change d'une version à l'autre de Python.
|
||||
- Les chaînes ne contenant que des [a-zA-Z0-9_] sont internées.
|
||||
|
||||
|
||||
## IEEE 754
|
||||
|
||||
```python
|
||||
f"http://{.1 + .2}.com"
|
||||
```
|
||||
|
||||
Notes:
|
||||
|
||||
Notez ! Et au besoin utilisez le module Decimal.
|
||||
|
||||
|
||||
## Définir vos propres exceptions
|
||||
|
||||
Il suffit d'hériter d'`Exception`, rien de plus.
|
||||
|
||||
```
|
||||
>>> class DBError(Exception): pass
|
||||
...
|
||||
>>> raise DBError("No such entry")
|
||||
Traceback (most recent call last):
|
||||
File "<stdin>", line 1, in <module>
|
||||
__main__.DBError: No such entry
|
||||
```
|
||||
|
||||
Notes:
|
||||
|
||||
library/exceptions.html → hierarchy
|
||||
|
||||
|
||||
## try, finally, else, except
|
||||
|
||||
Dans quel ordre ?
|
||||
|
||||
Notes: Oui, il y a un else ici aussi.
|
||||
|
||||
|
||||
## try, except, else, finally
|
||||
|
||||
## Les décorateurs
|
||||
|
||||
```python
|
||||
with open("/etc/hosts") as f:
|
||||
f.read()
|
||||
```
|
||||
|
||||
Notes:
|
||||
|
||||
En initiation on apprend a les utiliser.
|
||||
En avancé on apprend à en faire.
|
||||
|
||||
## Les décorateurs
|
||||
|
||||
Faire ses propres décorateurs.
|
||||
|
||||
Notes:
|
||||
|
||||
Leur faire implémenter un décorateur @clock.
|
||||
```python
|
||||
def clock(func):
|
||||
def clocked(*args):
|
||||
t0 = time.perf_counter()
|
||||
result = func(*args)
|
||||
elapsed = time.perf_counter() -t0
|
||||
name = func.__name__
|
||||
arg_str = ', '.join(repr(arg) for arg in args)
|
||||
print(f"[{elapsed:.08f}s] {name}({arg_str}) -> {result!r}")
|
||||
return result
|
||||
return clocked
|
||||
```
|
||||
|
||||
|
||||
## Les décorateurs
|
||||
|
||||
Faire ses décorateurs paramétrés.
|
||||
|
||||
Notes:
|
||||
|
||||
Leur faire implémenter @memoize qui prend paramètre une limite.
|
||||
|
||||
En profiter pour parler de `global`, `nonlocal`, et des closures.
|
||||
|
||||
|
||||
## Les décorateurs
|
||||
|
||||
Les utiliser pour leurs effets de bord.
|
||||
|
||||
Notes:
|
||||
|
||||
`@route("/")` par exemple.
