![]() ![]() I did a quick speed comparison and it was considerably faster than print(., file=f) when performing a large number of writes. If you are writing a lot of data and speed is a concern you should probably go with f.write(.). There is no point in using os.linesep on non-Windows systems, and it produces wrong results on Windows. And it's been that simple ever since the first port of Python to Windows. It's this simple: use \n which will be translated automatically to os.linesep. 'hi there' os.linesep is equivalent to 'hi there\r\n', which is NOT equivalent to 'hi there\n'. There is no way that it could produce the same outcome. > f.write('hi there' os.linesep) # same result as previous line ?Īs expected, os.linesep does NOT produce the same outcome as '\n'. Type "help", "copyright", "credits" or "license" for more information. Pass the encoding='utf-8' to the open() function to write UTF-8 characters into a file.Here is an exact unedited Python 2.7.1 interpreter session on Windows: Python 2.7.1 (r271:86832, Nov 27 2010, 18:30:46) on. ![]() Use write() and writelines() methods to write to a text file.Always close the file after completing writing using the close() method or use the with statement when opening the file.Use the open() function with the w or a mode to open a text file for appending.The following example shows how to write UTF-8 characters to a text file: ![]() To open a file and write UTF-8 characters to a file, you need to pass the encoding='utf-8' parameter to the open() function.
