# Crow's Nest
2+
3+
Write a program that will announce the appearance of something "off the larboard bow" to the captain of the ship.
4+
Note that you need to "a" before a word starting with a consonant:
5+
6+
```
7+
$ ./crowsnest.py narwhall
8+
Ahoy, Captain, a narwhall off the larboard bow!
9+
```
10+
11+
Or "an" before a word starting with a vowel:
12+
13+
```
14+
$ ./crowsnest.py octopus
15+
Ahoy, Captain, an octopus off the larboard bow!
16+
```
17+
18+
Given no arguments, the program should print a brief usage:
19+
20+
```
21+
$ ./crowsnest.py
22+
usage: crowsnest.py [-h] str
23+
crowsnest.py: error: the following arguments are required: str
24+
```
25+
26+
It should print a longer usage for `-h` and `--help`:
27+
28+
```
29+
$ ./crowsnest.py -h
30+
usage: crowsnest.py [-h] str
31+
32+
Crow's Nest -- choose the correct article
33+
34+
positional arguments:
35+
str A word
36+
37+
optional arguments:
38+
-h, --help show this help message and exit
39+
```
40+
41+
A passing test suite looks like this:
42+
43+
```
44+
$ make test
45+

# Picnic
2+
3+
Write a program that will correctly format the items we're taking on our picnic.
4+
For one item, it should print the one item:
5+
6+
```
7+
$ ./picnic.py sandwiches
8+
You are bringing sandwiches.
9+
```
10+
11+
For two items, place "and" in between:
12+
13+
```
14+
$ ./picnic.py sandwiches chips
15+
You are bringing sandwiches and chips.
16+
```
17+
18+
For three or more items, use commas and "and":
19+
20+
```
21+
$ ./picnic.py sandwiches chips cake
22+
You are bringing sandwiches, chips, and cake.
23+
```
24+
25+
If the `--sorted` flag is present, the items should first be sorted:
26+
27+
```
28+
$ ./picnic.py sandwiches chips cake --sorted
29+
You are bringing cake, chips, and sandwiches.
30+
```
31+
32+
If no items are given, print a brief usage:
33+
34+
```
35+
$ ./picnic.py
36+
usage: picnic.py [-h] [-s] str [str ...]
37+
picnic.py: error: the following arguments are required: str
38+
```
39+
40+
Respond to `-h` and `--help` with a longer usage:
41+
42+
```
43+
$ ./picnic.py -h
44+
usage: picnic.py [-h] [-s] str [str ...]
45+
46+
Picnic game
47+
48+
positional arguments:
49+
str Item(s) to bring

51+
optional arguments:
52+
-h, --help show this help message and exit
53+

54+
```
55+
56+

58+
