Use the keyword argument append=True to append lines to the file. The default is to overwrite the file. Warning: When you use this with Unicode data, if the encoding of the existing data in the file is different from the encoding you specify with the encoding= parameter, the result is mixed-encoding data, which can really confuse someone trying to read the file later.

The default behavior is to overwrite any existing file; to append instead, use the 'append=True' keyword argument.

Parameters: - text - str/unicode - The text to be written. - encoding - str - The Unicode encoding that will be used. This is ignored if 'text' isn't a Unicode string. - errors - str - How to handle Unicode encoding errors. Default is 'strict'. See help(unicode.encode) for the options.
