Bonjour,

Je ne savais plus comment noter une puissance en Python, et j'ai tapé
20^5 au lieu de 20**5. J'ai obtenu 17 en résultat.

J'ai testé d'autres valeurs :

 >>> x=[20^i for i in range (20)]
 >>> x
[20, 21, 22, 23, 16, 17, 18, 19, 28, 29, 30, 31, 24, 25, 26, 27, 4, 5, 6, 7]
 >>> x=[5^i for i in range (20)]
 >>> x
[5, 4, 7, 6, 1, 0, 3, 2, 13, 12, 15, 14, 9, 8, 11, 10, 21, 20, 23, 22]
 >>> x=[10^i for i in range (20)]
 >>> x
[10, 11, 8, 9, 14, 15, 12, 13, 2, 3, 0, 1, 6, 7, 4, 5, 26, 27, 24, 25], 
23, 16, 17, 18, 19, 28, 29, 30, 31, 24, 25, 26, 27, 4, 5, 6, 7]

Et la perplexité va grandissant :-)

Ma question est simple : quel est l'usage de ^ ?

Je vous remercie,
