python writeline
f = open('myfile', 'w') f.write('hi there-n') # python will convert -n to os.linesep f.close() # you can omit in most cases as the destructor will call it. Quoting from Python documentation regarding newlines: On output, if newlin, writelines expects a list of strings, while write expects a single string. line1 + "-n" + line2 merges those strings together into a single string before passing it to write . Note that if you have many lines, you may want to use "-n"
