Remove final '\n' from string variable

I'm trying to remove the final '\n' character from a string variable.

For example: 

string
string
string
\n

should simply become:

string
string
string

A lot of the examples I have seen do this for a file but not a variable.

Any help would be greatly appreciated!

In BASH you can do this to remove last newline:

eol=$'\n'
str="${s%$eol}"

You can use parameter expansion like this:

variable="${variable%$'\n'}"
