I have a multi-line string that I want to do an operation on each line, like so:
inputString = """Line 1
Line 2
Line 3"""
I want to iterate on each line:
for line in inputString:
doStuff()

inputString.splitlines()
Will give you a list with each item, the splitlines() method is designed to split each line into a list element.
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']
Use inputString.splitlines().
Why splitlines is better
splitlines handles newlines properly, unlike split.
It also can optionally return the newline character in the split result when called with a True argument, which is useful in some specific scenarios.
