如何为subprocess.Popen按顺序导入两个输入

Question

.exe需要依次输入两个输入，例如：

1. what is your input 1: File1
2. what is your input 2: File2

然后它会运行。我正在尝试使用

p = subprocess.Popen([.exe, File1], cwd=filename_dir, stdin=subprocess.PIPE, stdout=subprocess.PIPE)
time.sleep(1)
p.communicate(input=File2)

它没有用，有什么帮助吗？

p = subprocess.Popen([analyzer, filename1], cwd=filename_dir,        stdin=subprocess.PIPE, stdout=subprocess.PIPE)
time.sleep(1)

m=p.communicate(input=b'filename1\nfilename2\n')[0]
