Why does the following code not work?

```
data = [["4","5"],["3","7"]]
search = "4"
for sublist in data:
    if sublist[1] == "4":
        print ("there"), sublist
        break
    else:
        print("not there")
        break

```

Very sorry for all the confusion, everyone. I was trying to check the entire list and all its sublists and I didn't understand that this would only check the second element of the list, for I forgot Python has a 0th position for the first element. But, how would I check the entire list? remove the "break"s and [1]?
