Использование pexpect для автоматизации диалога manage.py syncdb

Question

Я пытаюсь использовать pexpect для автоматизации этого диалога. Также ниже представлена ​​программа python с использованием pexpect. Когда я запускаю код ... он ждет ввода в «Вы хотите создать его сейчас?» (Да/нет): «Затем перерыв с ошибкой. Ожидается «да» или «нет». Итак ... где я ошибался? Строка соответствует первому входу?

You just installed Django's auth system, which means you don't have any superusers defined. 
Would you like to create one now? (yes/no): 
Username (Leave blank to use 'root'): 
E-mail address: 
Password: 
Password (again): 

Python скрипт:

import pexpect 
child = pexpect.spawn ('python /opt/graphite/webapp/graphite/manage.py syncdb') 
child.expect ('Would you like to create one now? (yes/no):') 
child.sendline ('yes') 
child.expect ("""Username (Leave blank to use 'root'):""") 
child.sendline ('admin') 
child.expect ("E-mail address:") 
child.sendline ('david@gmail.com') 
child.expect ('Password:') 
child.sendline ('test') 
child.expect ('Password (again):') 
child.sendline ('test')

Answer 1

Я считаю, что pexpect использует синтаксис регулярных выражений.

child.expect ('Would you like to create one now.*?:') 

Я предполагаю, что вышеуказанное будет работать нормально.
Вы также можете избежать «?» и, возможно, скобки, чтобы получить лучшие результаты.

child.expect ('Would you like to create one now\? \(yes\/no\):') 

Answer 2

Синтаксис регулярного выражения также меня отключил. Вот код автоматизации, который работал для меня:

p = pexpect.spawn("python manage.py syncdb") 
p.logfile = sys.stdout 
p.expect(r"Would you like to create one now\? \(yes\/no\): ") 
p.sendline("yes") 
p.expect(r"Username \(leave blank to use '.*'\): ") 
p.sendline("admin") 
p.expect(r"Email address: ") 
p.sendline("admin@admin.com") 
p.expect(r"Password: ") 
p.sendline("admin") 
p.expect(r"Password \(again\): ") 
p.sendline("admin")
