If you have a "multiline" variable like

- Code: Select all
`a = "hello\nworld\nlinux\nrocks"`

Then you can use Python's

find method and substring (

[start:count]) context to extract a particular portion:

- Code: Select all
`print s[0:s.find("\n")]`

That will print

- Code: Select all
`hello`

You could also find out how many of your delimiters (string separators) there are in your "mulitline" variable.

- Code: Select all
`s.count("\n")`

Then ultimately you could also transform your "multiline" variable into an array using Python's

split function

- Code: Select all
`arr = s.split("\n")`

Then you could use a loop to go through those.

Here is a site with some good references on it for Python. You can see the definitions for each of those methods, like the

find method,

int find(sub [,start[,end]]), for example.

I hope that helps a little bit.
