pexpect - expecting pattern

How can I work with pexpect when the "expect" is not fixed:

Example: +DTMF: X, where X could be any integer from 0 to 9, such as +DTMF: 1.

I tried this but not success:

self.child.expect('+DTMF:', timeout=1)

I had a similar issue recently. Since the numbers at the end were important for me I found out that you could parse them by running those two lines.

child.expect('+DTFM: ')
value = child.read(1)

I assumed that you only had one digit, but you can specify the number of expected character on the child.read function.

Otherwise using regex will yield a more exact expect statement.

pexpect uses regular expressions, you can do this:

self.child.expect('\+DTMF: [0-9]', timeout=1)
