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

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))

Alternatively, you can try sys.stdin.read() that returns the whole input until EOF:

import sys
s = sys.stdin.read()
print(s)

Keep reading lines until the user enters an empty line (or change stopword to something else)

text = ""
stopword = ""
while True:
    line = raw_input()
    if line.strip() == stopword:
        break
    text += "%s\n" % line
print text
