It is not just a game... so what is the purpose of this tiny python project, you might be asking.

With this picnic_game project, I have been able to:

• write a program that accepts multiple positional arguments
• use if, elif, and else to handle conditional branching with three or more options
• find and alter items in a list
• format a list into a new string

The program that will correctly format the items we're taking on our picnic. For one item, it should print the one item:

$ ./picnic.py sandwiches
You are bringing sandwiches.

For two items, place "and" in between:

$ ./picnic.py sandwiches chips
You are bringing sandwiches and chips.

For three or more items, use commas and "and":

$ ./picnic.py sandwiches chips cake
You are bringing sandwiches, chips, and cake.

If the --sorted flag is present, the items should first be sorted:

$ ./picnic.py sandwiches chips cake --sorted
You are bringing cake, chips, and sandwiches.

If no items are given, print a brief usage:

$ ./picnic.py
usage: picnic.py [-h] [-s] str [str ...]
picnic.py: error: the following arguments are required: str

if the --comma flag is present, then the the Oxford comma is removed:

$ ./picnic.py sandwiches chips cake
You are bringing sandwiches, chips and cake.

if the --char flag is present, the items are seperated by the given character:

$ ./picnic.py sandwiches chips cake
You are bringing sandwiches: chips: cake

Respond to -h and --help with a longer usage:

$ ./picnic.py -h
usage: picnic.py [-h] [-s] str [str ...]
