expect with duplicated responses

When using the following (first time using expect) I have many responses with the same prompt. I took care of the first 20 of them as you can see below, however, the same prompt comes up again later during the install. I get complaints about duplicate values and the installer fails. How can I work around this (I wish this particular installer had a response file to configure that wasn't garbage)

Error:

 [WARNING]: While constructing a mapping from /etc/ansible/role/agent-install/tasks/main.yml, line 27, column 7, found a duplicate dict key (PRESS <ENTER> TO CONTINUE:). Using last defined value only.

Code:

- name: Execute the installer
  expect:
    command: "{{ directory }}/setup.bin"
    responses:
      'PRESS <ENTER> TO CONTINUE:':
        - ""

turns out I can't use this anyway due to the version of pexpect (booh!), but I would still like to know the answer for future use.

As the error say, you can only have one "PRESS <ENTER> TO CONTINUE:" so all the reposes must be merged into one.
responses is a dictionary, and dict can only have unique keys.

So, is this even possible in this situation where the same key comes up later?

Yes, you just add all the responses under the same key.
Responses don't need to be in the order they occurs, when expect sees the string(key) it takes the next element in the list(value) of that key.

Nice! I wasn't aware of that. I wasn't liking how large that expect task was getting. Thanks!
