6.1.2 File Object Creation

These functions create new file objects.

fdopen(fd[, mode[, bufsize]])
Return an open file object connected to the file descriptor fd. The mode and bufsize arguments have the same meaning as the corresponding arguments to the built-in open() function. Availability: Macintosh, Unix, Windows.

popen(command[, mode[, bufsize]])
Open a pipe to or from command. The return value is an open file object connected to the pipe, which can be read or written depending on whether mode is 'r' (default) or 'w'. The bufsize argument has the same meaning as the corresponding argument to the built-in open() function. The exit status of the command (encoded in the format specified for wait()) is available as the return value of the close() method of the file object, except that when the exit status is zero (termination without errors), None is returned. Availability: Unix, Windows.

Changed in version 2.0: This function worked unreliably under Windows in earlier versions of Python. This was due to the use of the _popen() function from the libraries provided with Windows. Newer versions of Python do not use the broken implementation from the Windows libraries.

tmpfile()
Return a new file object opened in update mode ("w+"). The file has no directory entries associated with it and will be automatically deleted once there are no file descriptors for the file. Availability: Unix.

For each of these popen() variants, if bufsize is specified, it specifies the buffer size for the I/O pipes. mode, if provided, should be the string 'b' or 't'; on Windows this is needed to determine whether the file objects should be opened in binary or text mode. The default value for mode is 't'.

popen2(cmd[, mode[, bufsize]])
Executes cmd as a sub-process. Returns the file objects (child_stdin, child_stdout). Availability: Unix, Windows. New in version 2.0.

popen3(cmd[, mode[, bufsize]])
Executes cmd as a sub-process. Returns the file objects (child_stdin, child_stdout, child_stderr). Availability: Unix, Windows. New in version 2.0.

popen4(cmd[, mode[, bufsize]])
Executes cmd as a sub-process. Returns the file objects (child_stdin, child_stdout_and_stderr). Availability: Unix, Windows. New in version 2.0.

This functionality is also available in the popen2 module using functions of the same names, but the return values of those functions have a different order.
