df:

```
   first     last                   email
0  Corey  Schafer  CoreMSchafer@gmail.com
1   Jane      Doe       JaneDoe@gmail.com
2   John      Doe       JohnDoe@gmail.com

```

From a big CSV file, how can I find a specific word like John, without knowing on what column or row he is? If there are several names with John, can I get all the info in the row or column where the names are?
