alphabet = "abcdefghijklmnopqrstuvwxyz"

def encrypt(txt):

   shift = int(input("Enter the shift: "))

   new_txt = ""

   for x in txt:

       if x in alphabet:

           if alphabet.index(x)+shift >= len(alphabet):

               new_txt += alphabet[(alphabet.index(x)+shift - len(alphabet))]

           else:

               new_txt += alphabet[alphabet.index(x)+shift]

       else:

           new_txt += x

   return new_txt

def decrpyt(txt):

   shift = int(input("Enter the known shift: "))

   new_txt = ""

   for x in txt:

       if x in alphabet:

           new_txt += alphabet[alphabet.index(x) - shift]

       else:

           new_txt += x

   return new_txt

print(encrypt("yellow dog."))

print(decrpyt("lryybj qbt."))

My code works with lowercase text only. If you need me to modify the code, I can do that. I tested my code with a shift of 13 in both the encryption and decryption. I hope this helps!

Shalnov [3]

When resizing an image or an object in a presentation, a user should not utilize the sizing handles in the middle of the sides or the bottom of the image. There's nothing wrong with resizing this way.

What modifier should you use on the members of a class so that they are not accessible to another class in a different package,
vova2212 [387]

The private modifier specifies that only other members of the same class can access the member. The protected modifier restricts access to the member to within its own package.

<h3>What are public and private modifiers?</h3>

The public access modifier permits code from both inside and outside the class to access the class's methods and properties, whereas the private modifier prevents outside code from accessing the class's methods and properties.

Thus, private modifier is the member.
