Question

**1. save_friendsdb**

This function takes two arguments, `friendsdb` and `filename`. It opens up the file specified by `filename` for writing and stores the information for each friend on a single line. Each line contains a friend's name followed by a tab, then the friend's height, and then a newline (\n). Be careful with this function -- don't accidentally overwrite any important files!

Sample calls should look like this:

```
>>> save_friendsdb(my_friends, "friendsdb.tsv")
```

But then when you have made this call, `friendsdb.tsv` (TSV stands for "tab-separated values") will contain this text:

```
bimmy 600
Ian Donald Calvin Euclid Zappa 175
```

(A drawback of Canvas here is that we can't include tabs -- those multiple spaces should be a single tab. Also, we are assuming that friends' names do not contain \t or \n characters.)
