Learning python and trying to solve 2 "problems" within a small app I am building.

Essentially I have 2 lists (let's assume that in real life the lists may not be in the same order)

```
first_name_age = [["bob", 8], ["frank", 10]]
first_name_height = [["bob", "48 inches"], ["frank", "53 inches"]]

```

The first problem I am trying to solve - what would be the best way to create "first\_name\_height\_age" where the array would be structured as:

```
first_name_height_age = [["bob", 8, "48 inches"], ["frank", 10, "53 inches"]]

```

The second question I have is - how would I append "Years old." to the 8 and 10 above? So that my new array would look like:

```
final = [["bob", "8 years old", "48 inches"], ["frank", "10 years old", "53 inches"]]

```
