Use pexpect to send user input

[alisha17]

I am trying to send the user input, which is the 'ENTER' key and from the documentation looks like child.sendline() should do the job. However the following code doesn't work. Could someone help me out?
I tried using child.sendline('y') etc. as well but doesn't seem to be be sending anything back.

        import pexpect
        import re
        import sys

        command = f"telliot-examples -a {account} -sa {signature_account} report -pwd {password} -spwd {signature_password} -tx {tx_type} -pf {priority_fee} -p {profit} -mf {max_fee}"

        child = pexpect.spawn(command, encoding='utf-8', timeout=5)

        find_phrase = "Press [ENTER] to confirm settings."
            
        a = child.expect([re.escape(find_phrase)])
        print(child.after)
        
        if child.after == find_phrase:
            print("here")   # works
            child.sendline()  # doesn't work
        else:
            print("The expected string was not found")
            sys.exit()
