im trying to code this caesar cipher decoder, but whenever the input message has any " "(spaces) it just print " " infinitely
[ps: just started coding]
already tried to change -if- to check if meslist[x] is equal to " ", but it doesent seems like a "valid" thing
here is the code:
import string
letras = list(string.ascii_lowercase)
message = input("qual sua menssagem codificada?")
cod = input("qual a numeração da cifra?")
meslist = list(message)
trans = True
num = len(meslist)
x = 0
while trans:
if num > x:
if meslist[x] in letras:
a = letras.index(meslist[x])
print(letras[a + 2])
x = x + 1
trans = True
else:
print(" ")
trans = True
elif num == 0:
trans = False'
just expecting for it to print it the right way.

I fixed the code as below :
while trans:
if num > x:
if meslist[x] in letras:
a = letras.index(meslist[x])
print(letras[a + 2])
x = x + 1
trans = True
else:
print(" ")
trans = True
# to increase x by 1, to take the next char. in the next loop
x = x + 1
# num == x means the end of the loop
elif num == x:
trans = False

I´m trying to solve this problem from the Qualification Round of the contest. It successfully solves the sample, but I receive a WA (Wrong Answer) for the cases. Can anyone figure out what is wrong with my code?
I tried my best looked solutions on google, but I could not find any difference between my code and the code of other contestants.

Python quiz - Where the user can add his questions

I'm making a quiz in Python where a user can add himself the questions and answers and specify the correct one.
I already did this
# Do you want to add another question version
from Question import Question
question_prompt = []
answer_list = []
def add_Question():
question = input('Add your question: ')
print(question)
test = int(input('If your question is correct. Enter 1 else enter 2: '))
if test == 1:
print('Type the answers propositions: ')
a = input('(a): ')
b = input('(b): ')
c = input('(c): ')
d = input('(d): ')
# print(a + '\n' + b + '\n' + c + '\n' + d )
answer = input('Which one is the correct answer? (a) (b) (c) or (d). Just type the letter ie. a: ').lower()
question_insert = f"{question} \n {a} \n {b} \n {c} \n {d}\n\n"
question_prompt.append(question_insert)
answer_list.append(answer)
listing = tuple(zip(question_prompt, answer_list))
questions = [Question(question_prompt[i],answer_list[i]) for i in range(0, len(listing))]
else :
question = input('add your question: ')
print(question)
test = int(input('if your question is correct. Enter 1 else enter 2: '))
return question, a,b,c,d,answer
def insert_question_prompt() :
again = int(input("Do you want to add another question. 1 = 'yes' and 2 = 'no' "))
while again == 1:
add_Question()
again = int(input("Do you want to add another question. 1 = 'yes' and 2 = 'no' "))
print(question_prompt)
def run_test(questions):
score = 0
for question in questions:
answer = input(question.prompt)
if answer == question.answer:
score += 1
print("Hey You got " + str(score) + "out of " + str(len(questions)) + "questions correct")
# questions = [Question(question_prompt[i],answer_list[i]) for i in range(0, len(listing))]
add_Question()
insert_question_prompt()
print(question_prompt)
print(answer_list)
In the function def insert_question_prompt() : I ask the user if he wants to insert another question and repeat the add_Question function.
The run_test function is to test the quiz. Play and access it
But I am unable to access question_prompt and answer_list in the run_test function even though they are not empty.
Basically, I'm blocked at level where the user can test the quiz ie Play and have the score.
Thanks for your help

Im trying to put in valid numbers into the board and meet all the conditions for the game.
The code doesnt run for some reason.
board = [
[0,0,6,9,0,5,0,1,0],
[9,7,0,0,1,2,3,0,5],
[0,2,0,0,0,4,8,6,0],

while zero_condition() == False and check_conditions == False and check_column() == False:
choose_cell()
print("you have finished soduko!!!")
I copy pasted all your code into a script and attempted to run it. If this is all your code, the first thing you are missing is a call to "begin_sudoku()" before your finishing print statement.
Afterwards, I ran it and was able to be asked whether to play, but entering "yes" still ended the game despite all three conditions being false. I found the last reason your game isn't running is because you are forgetting the parenthesis on "check_conditions()" when checking conditions in the while loop. I added the () to the end of it along with the call to begin_sudoku() and the game ran fine for me.
def begin_soduko():
answer= input("play soduko?")
if answer == "yes":
while zero_condition() == False and check_conditions() == False and check_column() == False:
choose_cell()
begin_soduko()
print("you have finished soduko!!!")
Replace your last code block with this and it should finally run.

Hei. I see that no problem in your code but the indent.
First. The code wit comment #handle the wrap around if num is larger than lenght of letters or less than 0 have to remove one indent(these must take in the same block with 2 desicions before). The translated = translated + letters[num] have to put at the same block with previous desicion
Second. The last else statement have to put at the same block with first if(if symbol in letters)
Here it is:
import pyperclip
message = "This is my secret message"
key = 13
mode = "encrypt"
letters = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
translated=""
message = message.upper()
for symbol in message:
if symbol in letters:
num = letters.find(symbol)
if mode == "encrypt":
num = num + key
elif mode == "decrypt":
num = num - key
if num >= len(letters):
num = num - len(letters)
elif num < 0:
num = num + len(letters)
translated = translated + letters[num]
else:
translated = translated + symbol
print(translated)
pyperclip.copy(translated)
The Output will be: GUVF VF ZL FRPERG ZRFFNTR

I have implemented the following code which works perfectly without any problem. But I am not satisfied with it because it doesn't look pretty? More than anything I feel like it doesn't look like pythonic way to do it.
So I thought I ll take suggestions from the stackoverflow community. This metod is getting its data from sql query which is in another method that method return a dictionary and based the data in that dictionary I am doing pattern match and counting process. I would like to do this in a pythonic way and return a better data structure.
Here is the code:
def getLaguageUserCount(self):
bots = self.getBotUsers()
user_template_dic = self.getEnglishTemplateUsers()
print user_template_dic
user_by_language = {}
en1Users = []
en2Users = []
en3Users=[]
en3Users=[]
en4Users=[]
en5Users=[]
en_N_Users=[]
en1 = 0
en2 = 0
en3 = 0
en4 = 0
en5 = 0
enN = 0
lang_regx = re.compile(r'User_en-([1-5n])', re.M|re.I)
for userId, langCode in user_template_dic.iteritems():
if userId not in bots:
print 'printing key value'
for item in langCode:
item = item.replace('--','-')
match_lang_obj = lang_regx.match(item)
if match_lang_obj is not None:
if match_lang_obj.group(1) == '1':
en1 += 1
en1Users.append(userId)
if match_lang_obj.group(1) == '2':
en2 += 1
en2Users.append(userId)
if match_lang_obj.group(1) == '3':
en3 += 1
en3Users.append(userId)
if match_lang_obj.group(1) == '4':
en4 += 1
en4Users.append(userId)
if match_lang_obj.group(1) == '5':
en5 += 1
en5Users.append(userId)
if match_lang_obj.group(1) == 'N':
enN += 1
en_N_Users.append(userId)
else:
print "Group didn't match our regex: " + item
else:
print userId + ' is a bot'
language_count = {}
user_by_language['en-1-users'] = en1Users
user_by_language['en-2-users'] = en2Users
user_by_language['en-3-users'] = en3Users
user_by_language['en-4-users'] = en4Users
user_by_language['en-5-users'] = en5Users
user_by_language['en-N-users'] = en_N_Users
user_by_language['en-1'] = en1
user_by_language['en-2'] = en2
user_by_language['en-3'] = en3
user_by_language['en-4'] = en4
user_by_language['en-5'] = en5
user_by_language['en-n'] = enN
return user_by_language
You can avoid all these lists and add the data directly to the user_by_language dict.
I would define it as:
user_by_language = collections.defaultdict(list)
After matching the regex, just do this:
user_by_language['en-%s-users' % match_lang_obj.group(1)].append(userId)
In the end, you grab all the lengths of these elements and save them as en-1, en-2...
