使用 pexpect库.这是Expect功能的Python版本.

Use the pexpect library. This is the Python version for Expect functionality.

示例:

child = pexpect.spawn('Some command that requires password')
child.expect('Enter password:')
child.sendline('password')
child.expect(pexpect.EOF, timeout=None)
cmd_show_data = child.before
cmd_output = cmd_show_data.split('\r\n')
for data in cmd_output:
    print data

Pexpect附带许多示例，可供您学习.要使用interact()，请从示例中查看script.py:

Pexpect comes with lots of examples to learn from. For use of interact(), check out script.py from examples:

(对于Windows，有pexpect的替代方法.)

(For Windows, there is an alternative to pexpect.)

• 我是否可以在Windows上使用Expect而无需安装Cygwin?
