在 shell 上提示时如何制作 python 脚本类型

Question

类似的东西：How to make python script press 'enter' when prompted on Shell

就像那个问题，如果我有test_enter.py：

print("press enter...")
input()
print("yay!")

还有这个文件：

from subprocess import Popen, PIPE
p = Popen(['python test_enter.py'], stdin=PIPE, shell=True)
p.communicate(input=b'\n')

但我希望它输入一些内容，然后按“回车”，而不只是换行。这可能吗？

要调用的脚本：

print("write something here")
inserted_string = input()
print("You wrote: " + inserted_string)

调用者脚本：

from subprocess import Popen, PIPE
import sys

print("custom insert here...")
inserted1 = input()

if len(sys.argv) > 1:
  inserted2 = sys.argv[1]
else:
  inserted2 = 'nothing here'

p1 = Popen(['python script_to_call.py'], stdin=PIPE, shell=True)
p1.communicate(input=b'standard string\n')

print(" --- ")

p2 = Popen(['python script_to_call.py'], stdin=PIPE, shell=True)
p2.communicate(input=inserted1.encode('utf-8') + b'\n')

print(" --- ")

p3 = Popen(['python script_to_call.py'], stdin=PIPE, shell=True)
p3.communicate(input=inserted2.encode('utf-8') + b'\n')

运行命令

python caller.py "string got from parameter"

输出：

custom insert here...
string got from input

write something here
You wrote: standard string
 --- 
write something here
You wrote: string got from input
 --- 
write something here
You wrote: string got from parameter
