Python 的 pexpect 模块的问题

[mikefy]

使用这个模块进行 scp 命令的时候, 因为 ip 不在已知的主机列表中, 所以有一个需要输入 yes/no 的动作,

The authenticity of host 'X.X.X.X (X.X.X.X)' can't be established.

ECDSA key fingerprint is SHA256:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX.

ECDSA key fingerprint is MD5:67:2a:d8:dc:13:9XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX.

Are you sure you want to continue connecting (yes/no)?

我的判断是: i = child.expect(['denied', 'yes/no', 'assword', '100%'], timeout=10)

但是每次这里的检测都过不去, 不知道为什么

pexpect.exceptions.TIMEOUT: Timeout exceeded.
