J’ai mis quelques temps \u00e0 le d\u00e9couvrir ce built-in, pour l’oublier presque aussi vite. Je l’ai red\u00e9couvert au d\u00e9tour d’une conversation python au boulot.<\/p>\n

A quoi sert-il donc ? En fait ‘\u00e0 rien’, simplement \u00e0 all\u00e9ger l’\u00e9criture (niveau perf, je ne sais pas si cela change quelque chose, \u00e7a par contre)<\/p>\n

any prend un seul param\u00eatre, un iterable et renvoie True d\u00e9s que l’un des iterables est vrai. Si je cite la doc python, any est \u00e9quivalent \u00e0 une fonction d\u00e9finie comme suit :<\/p>\n

def<\/span> any<\/span>(<\/span>iterable)<\/span>:
\n    for<\/span> element in<\/span> iterable:
\n        if<\/span> element:
\n            return<\/span> True<\/span>
\n    return<\/span> False<\/span><\/div><\/div>\n

un petit exemple sur une recherche de sous-chaine dans des chaines :<\/p>\n

avant :<\/p>\n

for<\/span> word in<\/span> list_words:
\n    if<\/span> word.find<\/span>(<\/span>substring)<\/span> !=<\/span> -1<\/span>:
\n        return<\/span> True<\/span>
\nreturn<\/span> False<\/span><\/div><\/div>\n

apr\u00e8s :<\/p>\n

return<\/span> any<\/span> (<\/span> word.find<\/span>(<\/span>substring)<\/span> !=<\/span> -1<\/span> for<\/span> word in<\/span> list_words )<\/span><\/div><\/div>\n

C’est plus l\u00e9ger, tout le monde sera d’accord avec moi \u2026<\/p>\n

Et puis, vu qu’on y est, il existe aussi le built-ins all qui prend lui aussi un it\u00e9rable en param\u00e8tre et renvoie True si tout les \u00e9l\u00e9ments de l’it\u00e9rable sont True.
