How do I read multiple lines of raw input in Python?

Question

I want to create a Python program which takes in multiple lines of user input. For example:

This is a multilined inp         


        

Answer 1

sentinel = '' # ends when this string is seen
for line in iter(raw_input, sentinel):
    pass # do things here

To get every line as a string you can do:

'\n'.join(iter(raw_input, sentinel))

---

Python 3:

'\n'.join(iter(input, sentinel))
