我有一个具有多个用户输入的脚本（使用python输入功能），我想编写另一个脚本来执行前一个脚本并为其提供输入。
我尝试将子进程模块与Popen一起使用，但出现了完全不同的错误，即TypeError和EOF错误。
~$ python3 importPasswords.py
Traceback (most recent call last):
File "importPasswords.py", line 68, in <module> child.communicate(input="3")
File "/usr/lib/python3.6/subprocess.py", line 843, in communicate stdout, stderr = self._communicate(input, endtime, timeout)
File "/usr/lib/python3.6/subprocess.py", line 1499, in _communicate input_view = memoryview(self._input)
TypeError: memoryview: a bytes-like object is required, not 'str'
~$ Traceback (most recent call last):
File "PasswordGeneratorConsole.py", line 188, in <module> pgc = PasswordGeneratorConsole()
File "PasswordGeneratorConsole.py", line 20, in __init__ self.start()
File "PasswordGeneratorConsole.py", line 24, in start choice = input("What do you want to do: [1] save a password, [2] generate a new password or [3] search a password: ")
EOFError: EOF when reading a line
第一个文件的输入行：
choice = input("What do you want to do: [1] save a password, [2] generate a new password or [3] search a password: ")
另一个文件：
from subprocess import Popen, PIPE
p = Popen(['python3', 'PasswordGeneratorConsole.py'], stdin=PIPE, stdout=PIPE)
p.communicate("3")
我希望第二个程序为第一个程序提供3作为输入。
