well, i started messing around with dictionaries, yet, most of the pages i found about them always talk about getting only one word out of it and turning it vice versa, i've been playing with that code for a few hours: -
#dics

Encryption={',':'hy{;',' ':'h4x0r2','':'zomg','?':'bko','a':'ika','b':'d0v','c':'ino', 'd':'maw', 'e':'aon', 'f':'que', 'g':'kip', 'h':'an[', 'i':'bf}', 'j':'ana&', 'k':'%d#', 'l':'d^f', 'm':'[d:w]', 'n':'ko[p', 'o':'{par:', 'p':'nt|;', 'q':'bz&$', 'r':'le{}', 's':'ak+', 't':'joq%', 'u':'f%(', 'v':'@!', 'w':'hg^*', 'x':'yu#', 'y':'fy%s', 'z':'mos@'}
-
Decryption=dict(zip(Encryption.values(), Encryption.keys()))
-

try:

-
for mail in y:

lol += Decryption[mail]
-
print lol
-
except KeyError:

print 'These keys are not in the dictionary!'

trying to get an output from the reversed dictionary is just not working, keeps giving me KeyErrors, even i enter only 1 word that is IN the dictionary...
maybe it's because didn't use conventional letters, but still, how do i decrypt?
plz help
#Note: the Encryption works perfectly, the Decryption Doesn't.
I'm using python 2.5 (python 3 is weird O|o)

You are iterating on the string in decrypt(). That means you are considering only one letter at a time. Try this instead: - def decrypt(y):
-
for key in Decryption:
-
if key in y:
-
while True:
-
try:
-
i = y.index(key)
-
y = y[:i]+Decryption[key]+y[i+len(key):]
-
except:
-
break
-
return y
Example: - >>> s = encrypt('temple of doom')
-
>>> s
-
'joq%aon[d:w]nt|;d^faonh4x0r2{par:queh4x0r2maw{par:{par:[d:w]'
-
>>> decrypt(s)
-
'temple of doom'
-
>>>
Oh, so this is how it's done...
the return is bugging it =/ changed it to print

There probably is a better way to do it. :)
I generally prefer to return an object from a function then format the output as required. Using an IDE makes testing code much easier. In your case: - s = encrypt('temple of doom')
-
print s
-
print decrypt(s)
i need to decrypt binary, which example will work in that case?
is there a shortcut to create a Bin dictionary?
