The '...' is the interpreter's way of telling you that you are in a block, e.g. a function definition, with statement, etc. The '\n' you see in the middle of the string is the newline character. If you try to print the string, the expected happens: >>> d = """dddddddddddddddd .... ddddddddddddddddddddddd""" >>> d 'dddddddddddddddd\nddddddddddddddddddddddd' >>> print(d) dddddddddddddddd ddddddddddddddddddddddd Geremy Condra

You seem to be confused by the presentation of the interactive interpreter. That text is a prompt. > I need a way to assign large blocks of text to a variable w/out > special formatting. That's what triple-quoted string syntax is for. You would do well to work through the entirety of the Python tutorial <URL:http://docs.python.org/tutorial/>. Take the time to actually perform each exercise and experiment until you understand the concept being presented, before moving on. -- \ “I find the whole business of religion profoundly interesting. | `\ But it does mystify me that otherwise intelligent people take | _o__) it seriously.” —Douglas Adams | Ben Finney

Thanks but what if the string is 500 lines. Seems it would be hard to put a "\" manually at the end of every line. How could i do that?
