Remove all line breaks from a long string of text

Question

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 and delete all line breaks to make it a single line of text   My method for acquiring the string is very simple   string   raw input  Please enter string       Is there a different way I should be grabbing the string from the user   I m running Python 2 7 4 on a Mac   P S  Clearly I m a noob  so even if a solution isn t the most efficient  the one that uses the most simple syntax would be appreciated

The canonic answer  in Python  would be   s      join s splitlines     It splits the string into lines  letting Python doing it according to its own best practices   Then you merge it  Two possibilities here   replace the newline by a whitespace      join    or without a whitespace     join

You can split the string with no separator arg  which will treat consecutive whitespace as a single separator  including newlines and tabs   Then join using a space   In       join   n nsome    text  r n with multiple whitespace  split    Out   some text with multiple whitespace    https   docs python org 2 library stdtypes html str split

The problem with rstrip is that it does not work in all cases  as I myself have seen few   Instead you can use - text  text replace   n       this will remove all new line  n with a space   Thanks in advance guys for your upvotes

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    gt  gt  gt  mystr   raw input  please enter string     please enter string  hello world  how do i enter line breaks   gt  gt  gt    pressing enter didn t work         gt  gt  gt  mystr  hello world  how do i enter line breaks    gt  gt  gt  mystr replace           helloworld howdoienterlinebreaks    gt  gt  gt    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
