Bonjour,
J'aimerai savoir comment écrire se programme avec un dictionnaire car ici avec les boucles le programme est très long et très répétitif car il test toutes les lettres avant de trouvé la bonne :s



with open("test32.txt", "r") as source:
chaine = source.read()

chaine1 = ""

for c in chaine:
if c=="a":
chaine1 += "11"
elif c=="b":
chaine1 +="12"
elif c=="c":
chaine1 +="13"
elif c=="d":
chaine1 +="14"
.....

Voici en pièce jointe le programme car je ne sais pas comment afficher le programme dans le cadre
Merci

Avec un dictionnaire c'est facilement faisable

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
6
7
8
9
10
11
12
13
>>> ord('a')
97
>>> ord('z')
122
>>> dico = {}
>>> for n in range(97, 123):
...     dico[chr(n)] = str(n-86)
... 
>>> dico
{'z': '36', 'y': '35', 'x': '34', 's': '29', 'r': '28', 'q': '27', 'p': '26', 'w': '33', 'v': '32', 'u': '31', 't': '30', 'k': '21', 'j': '20', 'i': '19', 'h': '18', 'o': '25', 'n': '24', 'm': '23', 'l': '22', 'c': '13', 'b': '12', 'a': '11', 'g': '17', 'f': '16', 'e': '15', 'd': '14'}
>>> 
>>> dico['a']
'11'

Ce que je voudrais faire en gros c'est prendre une chaine de caractère et remplacer chaque termes par d'autres termes définies dans le dictionnaire:

dic_crypt=("\n":"00"),("\"":"01"),("!":"02"),(" ":"03"),("%":"04"),("&":"05"),("\'":"06"),("(":"07"),(")":"08"),("*":"09"),("+":"10"),(",":"11"),("-":"12"),(".":"13"),("/":"14"),("0":"15"),("1":"16"),("2":"17"),("3":"18"),("4":"19"),("5":"20"),("6":"21"),("7":"22"),("8":"23"),("9":"24"),(":":"25"),(";":"26"),("<":"27"),("=":"28"),(">":"29"),("?":"30"),("@":"31"),("A":"32"),("B":"33"),("C":"34"),("D":"35"),("E":"36"),("F":"37"),("G":"38"),("H":"39"),("I":"40"),("J":"41"),("K":"42"),("L":"43"),("M":"44"),("N":"45"),("O":"46"),("P":"47"),("Q":"48"),("R":"49"),("S":"50"),("T":"51"),("U":"52"),("V":"53"),("W":"54"),("X":"55"),("Y":"56"),("Z":"57"),("[":"58"),("]":"59"),("a":"60"),("b":"61"),("c":"62"),("d":"63"),("e":"64"),("f":"65"),("g":"66"),("h":"67"),("i":"68"),("j":"69"),("k":"70"),("l":"71"),("m":"72"),("n":"73"),("o":"74"),("p":"75"),("q":"76"),("r":"77"),("s":"78"),("t":"79"),("u":"80"),("v":"81"),("w":"82"),("x":"83"),("y":"84"),("z":"85"),("{":"86"),("}":"87"),("~":"88"),("à":"89"),("â":"90"),("ç":"91"),("é":"92"),("è":"93"),("ê":"94"),("î":"95"),("ï":"96"),("ô":"97"),("ù":"98"),("û":"99")

Comme ceux la est que par exemple si j'ai "Coucou" cela me donne 627480627480. J'ai deja reussi a le faire mais avec .replace mais cela prend beaucoup de place :s

J'ai du mal à comprendre votre problème

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

result = ''
for letter in "Coucou":
    result += dic_crypt[letter]
print(result)

Écrire une commande qui ouvre un fichier texte, parcourir l'ensemble du fichier, remplacer certains caractères par d'autres que j'ai au préalable mis dans un dictionnaire qui est celui-ci:

dic_crypt={"\n":"00","\"":"01","!":"02"," ":"03","%":"04","&":"05","\'":"06","(":"07",")":"08","*":"09","+":"10",",":"11","-":"12",".":"13","/":"14","0":"15","1":"16","2":"17","3":"18","4":"19","5":"20","6":"21","7":"22","8":"23","9":"24",":":"25",";":"26","<":"27","=":"28",">":"29","?":"30","@":"31","A":"32","B":"33","C":"34","D":"35","E":"36","F":"37","G":"38","H":"39","I":"40","J":"41","K":"42","L":"43","M":"44","N":"45","O":"46","P":"47","Q":"48","R":"49","S":"50","T":"51","U":"52","V":"53","W":"54","X":"55","Y":"56","Z":"57","[":"58","]":"59","a":"60","b":"61","c":"62","d":"63","e":"64","f":"65","g":"66","h":"67","i":"68","j":"69","k":"70","l":"71","m":"72","n":"73","o":"74","p":"75","q":"76","r":"77","s":"78","t":"79","u":"80","v":"81","w":"82","x":"83","y":"84","z":"85","{":"86","}":"87","~":"88","à":"89","â":"90","ç":"91","é":"92","è":"93","ê":"94","î":"95","ï":"96","ô":"97","ù":"98","û":"99"}

Voilà j'ai reussi le programme je vous montres a quoi il ressemble

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

with open("Readme.txt", "r") as source:
	contenu = source.read()

for cle in index:
	contenu = contenu.replace(cle, index[cle])
print(contenu)	
 
with open("test_codé.txt", "w") as destination:
	destination.write(contenu)

Mais voila j'ai une autre question qui est la suivante je voudrais modifier le programme suivant:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

6
7
8
9
10
11
with open("test_codé.txt", "r") as source:
	contenu = source.readline()
 
index={"00":"\n", "01":"\"", "02":"!", "03":" ", "04":"%", "05":"&", "06":"\'", "07":"(", "08":")", "09":"*", "10":"+", "11":",", "12":"-", "13":".", "14":"/", "15":"0", "16":"1", "17":"2", "18":"3", "19":"4", "20":"5", "21":"6", "22":"7", "23":"8", "24":"9", "25":":", "26":";", "27":"<", "28":"=", "29":">", "30":"?", "31":"@", "32":"A", "33":"B", "34":"C", "35":"D", "36":"E", "37":"F", "38":"G", "39":"H", "40":"I", "41":"J", "42":"K", "43":"L", "44":"M", "45":"N", "46":"O", "47":"P", "48":"Q", "49":"R", "50":"S", "51":"T", "52":"U", "53":"V", "54":"W", "55":"X", "56":"Y", "57":"Z", "58":"[", "59":"]", "60":"a", "61":"b", "62":"c", "63":"d", "64":"e", "65":"f", "66":"g", "67":"h", "68":"i", "69":"j", "70":"k", "71":"l", "72":"m", "73":"n", "74":"o", "75":"p", "76":"q", "77":"r", "78":"s", "79":"t", "80":"u", "81":"v", "82":"w", "83":"x", "84":"y", "85":"z", "86":"{", "87":"}", "88":"~", "89":"à", "90":"â", "91":"ç", "92":"é", "93":"è", "94":"ê", "95":"î", "96":"ï", "97":"ô", "98":"ù", "99":"û"}
 
for cle in index:
	contenu = contenu.replace(cle, index[cle])
print(contenu)	
 
with open("test36.txt", "w") as destination:
	destination.write(contenu)

Sur celui-ci si vous l’avez bien compris il sert a décrypter le premier texte qui a été crypter avec le programme suivant. Mon problème est le suivant je souhaiterai que la boucle prenne les termes 2 par 2

J te remercie de ton aide c'est sympa, mais vu que je débute connais pas forcement tout ce que tu as écris il me reste plus qu'a comprendre 2 ou 3 petite chose et j'aurai atteint mon but.

Je tiens a remercier toutes les personnes qui m'ont aidés sur ceux post
Je vous en remercie
