decode regex search

[misterlisty]

response=lteM.send_at_cmd('AT+CEREG?')#Check networks
print(response)
indexs=re.search("2,1",response)

The result is this <match num=1> but how do i decode this ie extract 1 from this?

@misterlisty for instance:
indexs.group(0)
But if you search for a fixed string, you can as well use index, e.g.

try:
    found = response.index("2,1")
except:
    found = -1

it returns either the position of the string or raises an error.
