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

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

Answer 2

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))

Answer 3

*I struggled with this question myself for such a long time, because I wanted to find a way to read multiple lines of user input without the user having to terminate it with Control D (or a stop word). In the end i found a way in Python3, using the pyperclip module (which you'll have to install using pip install) Following is an example that takes a list of IPs *

import pyperclip

lines = 0

while True:
    lines = lines + 1 #counts iterations of the while loop.

    text = pyperclip.paste()
    linecount = text.count('\n')+1 #counts lines in clipboard content.

    if lines <= linecount: # aslong as the while loop hasn't iterated as many times as there are lines in the clipboard.
        ipaddress = input()
        print(ipaddress)

    else:
        break

For me this does exactly what I was looking for; take multiple lines of input, do the actions that are needed (here a simple print) and then break the loop when the last line was handled. Hope it can be equally helpful to you too.
