RC4 decryption with key in Python - python

I pulled this code from here for asp http://bytes.com/topic/access/insights/906671-rc4-encryption-algorithm-vba-vbscript, which i then run thru base64.
I am wonder if anyone can help me figure out how to write the decryption piece but in Python. As the decryption will happen on my Python Server Page.
Found this http://www.id-snippet.com/20801/python-rc4-cipher/, but it doesn't decrypt the RC4 asp from the first link.

Is there a shorter way to increment bd_address in python?

I wrote a python's function to increment BT device BD_ADDR by any value but my function can only work up to xx:xx:xx:xx:FE:FF. For example, original BD_ADDR = AA:BB:CC:DD:EE:FF --> incremented by 1 BD_ADDR = AA:BB:CC:DD:EF:00. Also is there a shorter way to do this without all if statements? any suggestions will be appreciated.
Below is the script:
def ba_incr(mac,incr):
old_bytes = mac[12:].split(":")
if (old_bytes[0] != "00"):
if (old_bytes[0] != "01" and old_bytes[0] != "0F"):
old_hex = str(old_bytes[0] + old_bytes[1])
incr_hex = hex(int(str(int(old_hex, base=16) + incr)))[2:]
new_bytes = str(incr_hex[:2]) + ":" + str(incr_hex[2:])
elif (old_bytes[0] == "0F" and old_bytes[1] == "FF") :
old_hex = str(old_bytes[0] + old_bytes[1])
incr_hex = hex(int(str(int(old_hex, base=16) + incr)))[2:]
new_bytes = str(incr_hex[:2]) + ":" + str(incr_hex[2:])
else:
old_hex = str(old_bytes[0] + old_bytes[1])
incr_hex = hex(int(str(int(old_hex, base=16) + incr)))[2:]
#print ("incremented hex",incr_hex)
new_bytes = "0" + str(incr_hex[:1]) + ":" + str(incr_hex[1:])
elif (old_bytes[0] == "00" and old_bytes[1] == "FF"):
old_hex = old_bytes[1]
#print ("old hex:",old_hex)
incr_hex = hex(int(str(int(old_hex, base=16) + incr)))[2:]
#print ("incremented hex:",incr_hex)
new_bytes = "01" + ":" + str(incr_hex[1:])
elif (old_bytes[0] == "00" and old_bytes[1][:1] == "0") and old_bytes[1][1:] != "F":
old_hex = old_bytes[1]
#print ("old hex:",old_hex)
incr_hex = hex(int(str(int(old_hex, base=16) + incr)))[2:]
#print ("incremented hex:",incr_hex)
new_bytes = old_bytes[0] + ":0" + str(incr_hex)
elif (old_bytes[0] == "00" and old_bytes[1] != "FF"):
old_hex = old_bytes[1]
#print ("old hex:",old_hex)
incr_hex = hex(int(str(int(old_hex, base=16) + incr)))[2:]
#print ("incremented hex:",incr_hex)
new_bytes = old_bytes[0] + ":" + str(incr_hex)[:2]
print ("mac after:", mac[:12] + new_bytes.upper())

You can probably try something like this:
Remove the ':' from the mac address
Convert the mac address to integer
Increment the integer value
Convert the integer to hex string
Insert back the ':' at the appropriate positions
Sample code that worked for me (for simplicity I am incrementing by 1). You may need to modify it to handle corner cases.
s = 'AA:BB:CC:DD:EE:FF'
s = s.replace(':', '')
val = int(s, 16)
val = val + 1
incr_s = hex(val)
incr_s = incr_s[2:].upper()
incr_s = ':'.join(incr_s[i:i+2] for i in range(0, len(incr_s), 2))
print(s)
print(incr_s)
Output:
AABBCCDDEEFF
AA:BB:CC:DD:EF:00

naive bayes classifier not working, prefers spam

I'm newer to Python and I've been trying to build a Naive Bayes classifier, but it seems to be prioritizing Spam over Ham. I know it's a lot to ask, but I was hoping someone who was familiar with Naive Bayes could point out what I've done wrong. As a side note: I skipped the denominator portion of the Naive Bayes equation; a common denominator shouldn't make a difference, right?
Here's a link to the guide I followed: https://towardsdatascience.com/unfolding-na%C3%AFve-bayes-from-scratch-2e86dcae4b01
And here's my code:
import csv
ham = 0
spam = 0
dictionarySpam = {}
dictionaryHam = {}
dictionaryTotal = {}
userString = input("Enter your string")
userString = userString.replace('.', ' ')
a = "!##$%^&*()_+=-?,><':;[]/"
userStringList = userString.split()
print(userStringList)
totalNumHam = 0
with open('spam.csv') as csv_file:
csv_reader = csv.reader(csv_file, delimiter=',')
for row in csv_reader:
if "ham" in row[0]:
ham += 1
elif "spam" in row[0]:
spam += 1
words = row[1].split()
for word in words:
word = word.replace('.', ' ')
for char in a:
word = word.replace(char, '')
dictionaryTotal[word.lower()] = dictionaryTotal.get(word.lower(), 0) + 1
if "ham" in row[0].lower():
dictionaryHam[word.lower()] = dictionaryHam.get(word.lower(), 0) + 1
elif "spam" in row[0].lower():
dictionarySpam[word.lower()] = dictionarySpam.get(word.lower(), 0) + 1
probHam = 1;
probSpam = 1;
print("HAM cases: ", ham)
print("SPAM cases: ", spam)
print(dictionaryHam)
print(dictionarySpam)
for item in userStringList:
if item in dictionaryHam:
probHam = probHam * ((dictionaryHam[item] + 1) / (sum(dictionaryHam.values()) + len(dictionaryTotal) + 1))
elif item not in dictionaryHam:
probHam = probHam * (1 / (sum(dictionaryHam.values()) + len(dictionaryTotal) + 1))
if item in dictionarySpam:
probSpam = probSpam * ((dictionarySpam[item] + 1) / (sum(dictionarySpam.values()) + len(dictionaryTotal) + 1))
elif item not in dictionaryHam:
probHam = probSpam * (1 / (sum(dictionarySpam.values()) + len(dictionaryTotal) + 1))
print("OUT: ", probHam)
probHam = probHam * (ham / (ham + spam))
probSpam = probSpam * (spam / (ham + spam))
print(probHam)
print(probSpam)
if probHam > probSpam:
print("This message is HAM")
else:
print("This message is SPAM")

I think you have messed up with your brackes in line:
probHam = probHam * ((dictionaryHam[item] + 1) / (sum(dictionaryHam.values()) + len(dictionaryTotal) + 1))

python files - who to open corectly

We have file with some math problems like: 46 + 19 (only + or - and it built up this way: number, space, sign, space, number) and we need to transform it into a new file and solve them (46 + 19 = 65). We don't know how many exercises there will be or the number of digits in every number. Here is my code:
enter code here
input_file = open(r'C:\try\bla.txt', 'r')
nums = input_file.read()
y = 0
dig1 = ''
dig2 = ''
sign = ''
x1 = nums.find(' ')
x2 = x1 + 1
def one(dig1, dig2, y):
for i in xrange(x1):
dig1 += nums[y]
y += 1
for m in xrange(abs(-x2)):
dig2 += nums[y + 1]
y += 1
sign = nums[x2]
if sign == '+':
sum = int(dig1) + int(dig2)
if sign == '-':
sum = int(dig1) - int(dig2)
print dig1, dig2, '=', sum
for a in xrange(0):
one(dig1, dig2, y)
one(dig1, dig2, y)
print 'f', nums[21]
#print dig1, dig2, '=', sum

Maybe you are want to get this(python3):
test.txt:
10 + 15
22 - 71
33 + 64
code:
import operator
op = {'+': operator.add, '-': operator.sub}
with open('test.txt', 'r') as f:
lines = f.readlines()
for i in lines:
args = i.split()
val = op[args[1]](int(args[0]), int(args[-1]))
r = f'{i.strip()} = {val}'
print(r)

Error in python replace. (AttributeError: 'tuple' object has no attribute 'replace')

Environment
I am using Python 3 and my OS is Windows 7.
I understand that some commands have changed from the transition from python 2.7 to 3 (What I have used).
Problem
The variable is temporary but is this:
(((((0, 7), 7), 8), 4), 5)
Here is the code to get rid of the brackets:
randy = randy.replace(")", "")
randy = randy.replace("(", "")
randy = randy.replace(" ", "")
When it tries to execute the replace function, I get thrown an error:
Traceback (most recent call last):
File "<string>", line 248, in run_nodebug
File "Criptic.py", line 134, in <module>
randy = randy.replace(")", "")

You have a tuple (a sort of list) of numbers, and you want to make that a string. You can't replace the brackets, they aren't a part of the variable, they are just a part of its representation.
Instead you should use join() and str()
result = " ".join(str(x) for x in randy)
However, this probably will not give the right result either, as it is a nested list of tuples. You probably mean: randy = randy + (rand,) instead if randy = randy,rand.

randy = randy,rand
This notation creates a tuple of two elements, tuples do not have a method called replace.
If you just want to concatenate the numbers into a list representation separated by commas, you could do this in your loop:
randy = []
num = 0
while num < finalcount:
rand = random.randrange(1,9)
randy.append(rand)
Then you remove the replace lines, and instead do this
randy = ",".join(randy)
to get a string that has the values separated by commas.
You should maybe add the output that you would like to get to your question, because at the moment it's not quite clear what you want to do exactly.

exam_st_date = (11, 12, 2014)
# Sample Output : The examination will start from : 11 / 12 / 2014
newtup = str(exam_st_date).replace(',', ' /')
print(newtup)
look at mine example should give you some results

To delete a list of characters, you could use the string's translate method:
import string
name = "(((((0, 7), 7), 8), 4), 5)"
table = string.maketrans( '', '', )
print name.translate(table,"()")
