Basically, I\'m asking the user to input a string of text into the console, but the string is very long and includes many line breaks. How would I take the user\'s string a

    How do you enter line breaks with raw_input? But, once you have a string with some characters in it you want to get rid of, just replace them.

    >>> mystr = raw_input('please enter string: ')
    please enter string: hello world, how do i enter line breaks?
    >>> # pressing enter didn't work...
    ...
    >>> mystr
    'hello world, how do i enter line breaks?'
    >>> mystr.replace(' ', '')
    'helloworld,howdoienterlinebreaks?'
    >>>
    

    In the example above, I replaced all spaces. The string '\n' represents newlines. And \r represents carriage returns (if you're on windows, you might be getting these and a second replace will handle them for you!).

    basically:

    # you probably want to use a space ' ' to replace `\n`
    mystring = mystring.replace('\n', ' ').replace('\r', '')
    

    Note also, that it is a bad idea to call your variable string, as this shadows the module string. Another name I'd avoid but would love to use sometimes: file. For the same reason.
