Most efficient way to write data out to a text file?

On 27 Jun 2002 02:01:35 GMT, rumours say that bokr at oz.net (Bengt

A minor correction, if I may add:

f.writelines(sl)
might be quite more efficient than
f.write(''.join(sl))

AFAIK the output is the same, as long as one remembers to insert the
necessary '\n' for line breaks where needed :)
