Python 非'sys.stdin.isatty（）时等待用户输入`

当我尝试使用一些cmd | main.py时：

if not sys.stdin.isatty():
    input() # how to wait for user input but not from pipe?

我已经读过了，但是我在windows中找不到

/dev/tty

，在python代码中处理它

如果这样调用，则管道连接到python脚本的stdin，而不是终端。用户的输入转到

some cmd

@klauds。必须通过某种方式将

/dev/tty

作为stdindirect获取。如果您这样调用它，则管道连接到python脚本的stdin，而不是终端。用户的输入转到
