No,I am not going to start with how to print 'Hello World' on screen using Python,You might have seen that a lot,if not you still haven't read any articles which teaches you python(So go back and check out my previous post)
So let's do something simple but cool thing with Python...
Cyphering/Encryption is a way of writing secret messages.
Can you recognize what I have written below?

Yes, the nuclear launch code ! just kidding
This is a mirror cypher.
In a mirror cypher the characters in the original text are replaced by it's mirrored character like A by Z, B by Y and so on... Looks simple eh? try decoding this on your own:

Don' waste your time,python to the rescue(this is what programming languages are for,doing repetitive tasks)
And here is my mirror.py program:
most of the lines are self explanatory.
Though I would explain the logic involved:
text.upper() converts the entered text to uppercase in order to unify the input text.
ord() returns the ASCII value of the argument character.
ord('A') is 65 and ord('Z') is 90, and chr(x)returns the ASCII character with ASCII value x.
i.e. ord(66) is 'B'
I used a logic to mirror the alphabet by using expression 155-ord(ch) which evalutes to 90 if ord(ch) is 65 and vice versa for all characters between 'A' and 'Z' just what we want.155 comes from the sum of the two extreme charactersASCII(65 and 90).and chr() is used to convert back to character.
SO YOU KNOW THE MIRROR CYPHER.
This can be used in any form you want,like a function or whatever.Comments are invited.And I will discuss more on cyphering if necessary.
