Write an algorithm which can increase the size of data passed into it without adding any redundant bits. (Think it as opposite of compressing the data)

 Make another algorithm to reverse the process above so we can get original data.

 write python scripts for both which at least can extend strings

What I have tried:

I have tried converting the ascii value of charachters so that compressing could be done

This is a homework question.
There is short-term benefit, but no long-term benefit, in us doing your homework for you.
Long-term benefit is what's important.
It's *your* homework - *you* need do do it so that *you* can learn programmimg.
