[solved] Multiline variable in python

[thedotmaster]

Say I have a variable such as this:

Code: Select all

a = "hello\nworld\nlinux\rocks"

it prints like this:

Code: Select all

hello
world
linux
rocks

Now, how can I tell the script just to display the first line, or the second line or whatever?
Would I have to use IF statements and loops or is there a function?

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.
