Exercice 1 : affectation et op\u00e9rations<\/strong><\/h4>\n\n\n\n

On consid\u00e8re les commandes suivantes :<\/p>\n\n\n\n

>>>a=3\n>>>a=a+1\n>>>a=a*2\n>>>a=a-2\n>>>a=a\/2\n>>>a=a**2<\/code><\/pre>\n\n\n\n
Que renvoie alors la commande ?<\/p>\n\n\n\n
>>>a\n...<\/code><\/pre>\n\n\n\n
Exercice 2 : division euclidienne<\/strong><\/h4>\n\n\n\n
Que renvoient les commandes suivantes ?<\/p>\n\n\n\n
>>>15\/\/2\n....\n>>>15%2\n....<\/code><\/pre>\n\n\n\n
Exercice 3 : boucles for … in range ()<\/strong><\/h4>\n\n\n\n
On consid\u00e8re les fonctions suivantes :<\/p>\n\n\n\n
def boucle1(n):\n    s=0\n    for i in range(n):\n        s+=i\n    return s\n\ndef boucle2(n):\n    s=0\n    for i in range(2,n):\n        s+=i\n    return s\n\ndef boucle3(n):\n    s=0\n    for i in range(1,n,2):\n        s+=i\n    return s\n\n<\/code><\/pre>\n\n\n\n
Apr\u00e8s ex\u00e9cution de celles-ci, que vont renvoyer les commandes suivantes :<\/p>\n\n\n\n
>>> boucle1(4)\n...\n>>> boucle2(5)\n...\n>>> boucle3(6)\n...<\/code><\/pre>\n\n\n\n
Exercice 4: tests conditionnels<\/strong><\/h4>\n\n\n\n
On consid\u00e8re les fonctions suivantes :<\/p>\n\n\n\n
def test1(x):\n    if x==4:\n        return True\n    else:\n        return False\n\ndef test2(n):\n    if n%2==0:\n        return n\/\/2\n    else :\n        return 3*n+1<\/code><\/pre>\n\n\n\n
Que renvoient les commandes suivantes ?<\/p>\n\n\n\n
>>> test1(3)\n...\n>>> test1(4)\n...\n>>> test1(\"4\")\n...\n>>>test2(3)\n...\n>>>test2(6)\n...<\/code><\/pre>\n\n\n\n
