Why Python language does not have a writeln() method?

Question

If we need to write a new line to a file we have to code:

file_output.write(\'Fooo line \\n\')

Are there any reasons why Python does not ha

Answer 1

It was omitted to provide a symmetric interface of the file methods and because a writeln() would make no sense:

• read() matches write(): they both operate on raw data
• readlines() matches writelines(): they both operate on lines including their EOLs
• readline() is rarely used; an iterator does the same job (except for the optional size param)

A writeline() (or writeln()) would be essentially the same as write(), since it wouldn't add an EOL (to match the behavior of writelines()).

The best way to mimic a print to a file is to use the special print-to-file syntax of Python 2.x or the file keyword argument of the print() function, like Daniel suggested.

Personally, I prefer the print >>file, ... syntax over file.write('...\n').
