The filename argument can be an actual filename (a str or bytes object), or an existing file object to read from or write to. The mode argument can be "r", "rb", "w", "wb", "a" or "ab" for binary mode, or "rt", "wt" or "at" for text mode. The default mode is "rb", and the default compresslevel is 9. For binary mode, this function is equivalent to the GzipFile constructor: GzipFile(filename, mode, compresslevel). In this case, the encoding, errors and newline arguments must not be provided. For text mode, a GzipFile object is created, and wrapped in an io.TextIOWrapper instance with the specified encoding, error handling behavior, and line ending(s). u tu bu Invalid mode: %ru0 Argument 'encoding' not supported in binary modeu.

At least one of fileobj and filename must be given a non-trivial value. The new class instance is based on fileobj, which can be a regular file, an io.BytesIO object, or any other object which simulates a file. It defaults to None, in which case filename is opened to provide a file object. When fileobj is not None, the filename argument is only used to be included in the gzip file header, which may includes the original filename of the uncompressed file. It defaults to the filename of fileobj, if discernible; otherwise, it defaults to the empty string, and in this case the original filename is not included in the header. The mode argument can be any of 'r', 'rb', 'a', 'ab', 'w', or 'wb', depending on whether the file will be read or written. The default is the mode of fileobj if discernible; otherwise, the default is 'rb'. A mode of 'r' is equivalent to one of 'rb', and similarly for 'w' and 'wb', and 'a' and 'ab'. The compresslevel argument is an integer from 0 to 9 controlling the level of compression; 1 is fastest and produces the least compression, and 9 is slowest and produces the most compression. 0 is no compression at all. The default is 9. The mtime argument is an optional numeric timestamp to be written to the stream when compressing. All gzip compressed streams are required to contain a timestamp. If omitted or None, the current time is used. This module ignores the timestamp when decompressing; however, some programs, such as gunzip, make use of it. The format of the timestamp is the same as that of the return value of time.time() and of the st_mtime member of the object returned by os.stat(). u tu Uu Invalid mode: {!r}u bu rbu nameu u modeu rs i id u wu aNT( u wu a(!
