Actually that doesn't really matter unless the loop is extremely big (> a million), since range is much faster than xrange for smaller values (which might be the more typical case). And I think range will be an iterator in the future, imitating the behavior of xrange. So it doesn't really matter anyway. >> However, how this C statement will be translated in Python? >> >> for (j = i = 0; i < (1 << H); i++) > > If H doesn't change during the loop, you can use: > > j = 0 > for i in xrange(1 << H): > ... > > If H can change, simply rewrite it into an obvious 'while' loop. I would suggest a different thing: rewrite it in python instead of translating it. -- http://mail.python.org/mailman/listinfo/python-list
