Subprocesses — Python 3.12.12 documentation

Because all asyncio subprocess functions are asynchronous and asyncio provides many tools to work with such functions, it is easy to execute and monitor multiple subprocesses in parallel.

IDLE — Python editor and shell — Python 3.15.0a2 documentation

By default, IDLE executes user code in a separate subprocess via a socket, which uses the internal loopback interface. This connection is not externally visible and no data is sent to or received from the internet.

Platform Support — Python 3.14.2 documentation

Subprocesses are not supported, i.e. loop.subprocess_exec() and loop.subprocess_shell() methods are not implemented. ProactorEventLoop has the following limitations:

shlex — Simple lexical analysis — Python 3.14.2 documentation

Executing commands quoted by this module on such shells can open up the possibility of a command injection vulnerability. Consider using functions that pass command arguments with lists such as subprocess.run() with shell=False. This idiom would be unsafe:

What’s New In Python 3.13 — Python 3.15.0a2 documentation

The subprocess module now uses the posix_spawn() function in more situations, including when close_fds is True (the default) on many modern platforms. This should provide a notable performance increase when launching processes on FreeBSD and Solaris.
