The read() function returns a string (object of type str), whether the file was opened in binary or text mode. Such objects are really a series of bytes which may or may not represent text in some encoding. (By contrast, objects of type unicode definitely do represent text in some Unicode encoding.) > I thought it was good only for variables, lists, etc. Variables? Do you mean tuples? len() works with any kind of sequence, and strings behave as a sequence of 1-byte strings. -- Ben Hutchings It is easier to write an incorrect program than to understand a correct one. -- http://mail.python.org/mailman/listinfo/python-list
