For question 2: decrypted by using: [code=python] str = "UMTPORMHTRNSDCYTDTIEPREITIPATAGRAIBS" count = 0 length = len(str)/2 while count<length: print str[len(str)-1-count], print str[count], count+=1 [/code] which give: S U B M I T A P R O G R A M T H A T P R I N T S …

That seems concise and simple to me.

can you post the error message that your compiler gave you? It may at least point you/us to a line where the error is instead of having to look through your code for it.

So you don't want a bubble sort then, you would rather have a selection sort that instead you find the largest value and put it in the end.

I would highly recommend downloading and using eclipse. It's free software and is a wonderful program to use and easy to set up.
