How to convert a string into bytes using bytes() in Python 3.5?

Question

I need a little help with the bytes();function in Python 3.5.
I hope I understand this properly, but bytes are a different way of storing a value, like 52 is 110100in binary. (Except binary is in bits right?) Anyway can somebody please tell me the following:

The proper syntax of bytes();(In use of a string)
Proper arguments the parameter "encoding" in bytes(str,encoding);
If I am completely mis-using this concept please tell me.

NOTE:

I am using this for weak cryptographic purposes. Please tell me how to:

Add a constant to every byte

And how to reverse aforesaid process.

How I am Using It:

str = "MyString";
data = bytes(str,*WHAT GOES HERE*);
print(data);

It's hard to tell if you're misusing the concept, since you don't show how you're using it. If you want basic info on how to use `bytes` you should read [the documentation](https://docs.python.org/3/library/functions.html#bytes). Otherwise, you should show a code example with an explanation of what you're trying to accomplish using `bytes`, and why it's not working as you planned. — BrenBarn, Dec 31 '16 at 19:05

@furas I need something that makes it harder to read from a file. — Expelliarmus, Dec 31 '16 at 19:09
Ok, heres how I want my program to flow: Get input, convert to bytes, add a constant to every byte, close file end program. — Expelliarmus, Dec 31 '16 at 19:11

By importing codecs I can encode and decode it easily! Thanks @Jean-François Fabre!

import codecs
str = "Done!";
codecs.encode(str,"rot-13")
