Python Ceaser_Cipher.py

The Below Program is very simple and written to encode and decode the name or any word . 

save it as "ceaser_cipher.py"

# i am about to write program - ceaser cipher 

cipher = {'a':'z' ,'b':'a', 'c':'b', 'd':'c', 'e':'d', 'f':'e', 'g':'f', 'h':'g', 'i':'h', 'j':'i', 'k':'j', 'l':'k', 'm':'l', 'n':'m', 'o':'n', 'p':'o', 'q':'p', 'r':'q', 's':'r', 't':'s', 'u':'t', 'v':'u', 'w':'v', 'x':'w', 'y':'x', 'z':'y',' ':'2'}

class ceaser_cipher:

        def __init__(self, name_cip):

                self.name_cip = name_cip

                self.encoded = ""

                self.decoded = ""

        def encode(self):

                global cipher

                for ch in self.name_cip:

                         self.encoded += cipher[ch]

                print self.encoded

        def decode(self):

                global cipher

                for ch in self.encoded:

                        for key in cipher :

                               if ch == cipher[key]:

                                         self.decoded += key

                print self.decoded

def call():

    ceaser = ceaser_cipher('prasanna loves python')

    ceaser.encode()

    ceaser.decode()

call()

Output : 

Encoded Message : oqzrzmmz2knudr2oxsgnm
After Decode : prasanna loves python

Run the Program by calling : python ceaser_cipher.py (works normal in Linux and Mac Users )

For Windows users : save the file in the particular area of python and then invoke it in command prompt - python ceaser_cipher.py after changing to the desired location .
