Inverse the Inversed

Computer Science Level 1

There are 26 letters, A to Z. The inverse code, replaces A as Z, B as Y, C as X .... and Z as A.

Use the inverse code to translate the message in the image.

Well, since I guess I'm not smart enough to notice the number of letters in the words of the code match the number of letters in the words of the answer here's a Python solution.

Python:

alphabet = 'abcdefghijklmnopqrstuvwxyz'
replace = {' ':' '}
for i in xrange(len(alphabet)):
    key = alphabet[i]
    new = alphabet[25-i]
    replace[key] = new
answer = ''
code = 'r zn z yiroorzmg uzm'
for letter in code:
    answer = answer + replace[letter]
print answer

If I am not wrong , you are the smartest man I've met here on Brilliant. You seem to have a Computer Code for all sorts of problem ,I really look up to you .

I am waiting for when you will write a computer code which will prove Fermat's Last Theorem !!!! $\ddot\smile$

Coding is easy. It's math like you and Jake Lai do that's difficult. As a computer scientist, I'm stuck with examining only the discrete and mathematicians like you are free to explore the infinite . For example, I could write a program to prove the validity for Fermat's Last Theorem for, say, n < 1,000,000, and a mathematician could prove it for all n. Computer science is a way of thinking that I enjoy, but I am limited by the resources of my machine, where you are not limited.

I am inclined to agree partially with you that CS is limited as I myself being a programmer (rookie one though,I know Java(NetBeans IDE),C++) but simulations are what make Computer Code rocking . You can save loads of time by writing code . Also remember : $\text{A computer is never WRONG}$ .

Let me change the topic just a bit . Can you suggest some source from where I can learn $\it{Python}$ from the Internet(if possible) ?

Thanks for the same !!

@A Former Brilliant Member – Here are some of my favorite resources:

Learn Python the Hard Way: http://learnpythonthehardway.org/book/

MIT's Introduction to Python: https://www.edx.org/course/introduction-computer-science-mitx-6-00-1x-0#.VNtP4np6jqA

MIT's Introduction to Algorithms: http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-006-introduction-to-algorithms-fall-2011/

Also, here's an awesome tip that nobody taught me early on: the built-in function dir is your best friend. You can use it on any module, variable, or value to print a dir ectory of the different things you can do with it. For example, if you want to find out everything that you can do with a string, just do the following:

1 2	`a = 'string' print dir(a)`

The Python documentation is also very thorough: https://docs.python.org/2.7/

If you have any questions, don't hesisitate to ask:

Moderator note:

This is basically an antisolution. You should show that the whole phrase is "I am a Brilliant fan".

Yup, that is why the cipher is completely insecure!

cipher would be more secure by removing all spacing as well as all caps
