It’s really just about which bytes are stored in a file. CR is a bytecode for carriage return (from the days of typewriters) and LF similarly, for line feed. It just refers to the bytes that are placed as end-of-line markers. Way more information, as always, on wikipedia.
You can use the print statement to do this without importing sys. The comma on the end of the print line prevents print from issuing a new line (you should note that there will be an extra space at the end of the output). The Python 3 SolutionSince the above does not work in Python 3, you can do this instead (again, … Read more
A line feed means moving one line forward. The code is \n.A carriage return means moving the cursor to the beginning of the line. The code is \r. Windows editors often still use the combination of both as \r\n in text files. Unix uses mostly only the \n. The separation comes from typewriter times, when you turned the wheel to move the paper to … Read more
What is the line? You can just have arguments on the next line without any problems: Otherwise you can do something like this: or with explicit line break: Check the style guide for more information. Using parentheses, your example can be written over multiple lines: The same effect can be obtained using explicit line break: Note that … Read more
From PEP 8 – Style Guide for Python Code: The preferred way of wrapping long lines is by using Python’s implied line continuation inside parentheses, brackets and braces. If necessary, you can add an extra pair of parentheses around an expression, but sometimes using a backslash looks better. Make sure to indent the continued line … Read more

It depends on how correct you want to be. \n will usually do the job. If you really want to get it right, you look up the newline character in the os package. (It’s actually called linesep.) Note: when writing to files using the Python API, do not use the os.linesep. Just use \n; Python automatically translates that to the proper newline … Read more
