How do I split a mult-line string into multiple lines?

Question

I have a multi-line string literal that I want to do an operation on each line, like so.

inputString = """Line 1
Line 2
Line 3"""

I want to do something like the following.

for line in inputString:
    doStuff()

Answer 1

for line in split(inputString, "\n"):
    doStuff()

Answer 2

inputString.splitlines()

Will give you an array with each item, the splilines() function is designed to split each line into an array element.

Answer 3

Like the others said:

inputString.split('\n')  # --> ['Line 1', 'Line 2', 'Line 3']

This is identical to the above, but the string module's functions are deprecated and should be avoided:

import string
string.split(inputString, '\n')  # --> ['Line 1', 'Line 2', 'Line 3']

Alternatively, if you want each line to include the break sequence (CR,LF,CRLF), use the splitlines method with a True argument:

inputString.splitlines(True)  # --> ['Line 1\n', 'Line 2\n', 'Line 3']
