file_unique_id
is equal.Note

telegram.PassportFile.get_file
, then it will automatically be decrypted as it downloads when you calldownload()
.

download
(custom_path: str = None, out: IO = None, timeout: int = None) → Union[str, IO]¶ Download this file. By default, the file is saved in the current working directory with its original filename as reported by Telegram. If the file has no filename, it the file ID will be used as filename. If a
custom_path
is supplied, it will be saved to that path instead. Ifout
is defined, the file contents will be saved to that object using theout.write
method.Note
custom_path
andout
are mutually exclusive.- If neither
custom_path
norout
is provided andfile_path
is the path of a local file (which is the case when a Bot API Server is running in local mode), this method will just return the path.
Parameters: - custom_path (
str
, optional) – Custom path. - out (
io.BufferedWriter
, optional) – A file-like object. Must be opened for writing in binary mode, if applicable. - timeout (
int
|float
, optional) – If this value is specified, use it as the read timeout from the server (instead of the one specified during creation of the connection pool).
Returns: The same object as
out
if specified. Otherwise, returns the filename downloaded to or the file path of the local file.Return type: str
|io.BufferedWriter
Raises: ValueError
– If bothcustom_path
andout
are passed.
