![]() Stdin=PIPE, and the stdin argument may not be used as well. Used, the internal Popen object is automatically created with If used it must be a byte sequence, or a string ifĮncoding or errors is specified or universal_newlines is true. The input argument is passed to municate() and thus to the TimeoutExpired exception will be re-raised after the child process If the timeoutĮxpires, the child process will be killed and waited for. The timeout argument is passed to municate(). ![]() PIPE for the stdout and/or stderr arguments. This does not capture stdout or stderr by default. Input and check, all the arguments to this function are passed through to Same as that of the Popen constructor - apart from timeout, The full function signature is largely the In Frequently Used Arguments (hence the use of keyword-only notation The arguments shown above are merely the most common ones, described below run ( args, *, stdin=None, input=None, stdout=None, stderr=None, shell=False, cwd=None, timeout=None, check=False, encoding=None, errors=None, env=None ) ¶ The run() function was added in Python 3.5 if you need to retainĬompatibility with older versions, see the Older high-level API section. Underlying Popen interface can be used directly. The recommended approach to invoking subprocesses is to use the run()įunction for all use cases it can handle.
