subprocess.stdin

• <stream.Writable>

代表子进程的 stdin 的 Writable Stream。

如果子进程等待读取其所有输入，则在通过 end() 关闭此流之前，子进程将不会继续。

如果子进程衍生时 stdio[0] 设置为 'pipe' 以外的任何值，则此将是 null。

subprocess.stdin 是 subprocess.stdio[0] 的别名。 这两个属性将引用相同的值。

• <stream.Writable>

A Writable Stream that represents the child process's stdin.

If a child process waits to read all of its input, the child will not continue until this stream has been closed via end().

If the child was spawned with stdio[0] set to anything other than 'pipe', then this will be null.

subprocess.stdin is an alias for subprocess.stdio[0]. Both properties will refer to the same value.
