super([type[, object-or-type]]) Return a proxy object that delegates method calls to a parent or sibling class of type. This is useful for accessing inherited methods that have been overridden in a class. The search order is same as that used by getattr() except that the type itself is skipped. The __mro__ attribute of the type lists the method resolution search order used by both getattr() and super(). The attribute is dynamic and can change whenever the inheritance hierarchy is updated. If

sum(iterable[, start]) Sums start and the items of an iterable from left to right and returns the total. start defaults to 0. The iterable‘s items are normally numbers, and the start value is not allowed to be a string. For some use cases, there are good alternatives to sum(). The preferred, fast way to concatenate a sequence of strings is by calling ''.join(sequence). To add floating point values with extended precision, see math.fsum(). To concatenate a series of iterables, consider using

timeout Timeout in seconds.

stdout Alias for output, for symmetry with stderr.

stderr Stderr output of the child process if it was captured by run(). Otherwise, None.

output Output of the child process if it was captured by run() or check_output(). Otherwise, None.

cmd Command that was used to spawn the child process.

exception subprocess.TimeoutExpired Subclass of SubprocessError, raised when a timeout expires while waiting for a child process. cmd Command that was used to spawn the child process. timeout Timeout in seconds. output Output of the child process if it was captured by run() or check_output(). Otherwise, None. stdout Alias for output, for symmetry with stderr. stderr Stderr output of the child process if it was captured by run(). Otherwise, None. New in version

exception subprocess.SubprocessError Base class for all other exceptions from this module. New in version 3.3.

wShowWindow If dwFlags specifies STARTF_USESHOWWINDOW, this attribute can be any of the values that can be specified in the nCmdShow parameter for the ShowWindow function, except for SW_SHOWDEFAULT. Otherwise, this attribute is ignored. SW_HIDE is provided for this attribute. It is used when Popen is called with shell=True.
