Program: ship$\_$planner.py

For this exam, you will need to write a program that can keep track of the composition of a container

ship and its cargo. Your program will compute the speed and draught of potential container ship

configurations. You will need to write two classes to represent the container ship, the containers that

carry the cargo.

Class: Container

An intermodal container or shipping container is a standardized container design that can be used

across different modes of transport, from ship to rail to truck, without unloading and reloading their

cargo. A container can come in two standard sizes: $1$ TEU and $2$ TEU. The container class should store

information about the specifications of each container: size and cargo type.

$$ Size $$ The size of the container: $1$ TEU or $2$ TEU

$$ Cargo Type $$ The type of cargo being carried:

o Frozen Food $$ FF

o Consumer Goods $$ CG

o Processed Goods $$ PG

o Raw Materials $$ RM

o Industrial Equipment $$ IE

Your container class must implement methods to get the size and cargo type:

$$ get$\_$size$()$ Returns the size of the container in TEU.

$$ get$\_$cargo$\_$type$()$ Returns the type of cargo.

Class: Container Ship

A container ship is a type of cargo ship that carries all its cargo in truck$-$sized containers. A container

ship$$s capacity is measured in twenty$-$foot equivalent units $($TEU$).$ Typically, a container ship$$s cargo is

split between $20-$foot $(1-$TEU$)$ and $40-$foot $(2-$TEU$)$ containers. The constructor for your container ship

class will take the following parameters as input:

$$ Maximum Capacity $$ The maximum number cargo capacity of the container ship in TEUs.

$$ Maximum Speed $$ The maximum speed the container ship can sail with no cargo in nautical

miles per hour $($knots$)$

$$ Minimum Draft $$ The minimum depth of the container ship with no cargo in meters.

$$ Maximum Draft $$ The maximum depth of the container ship with full cargo in meters.

Your container ship class should store a list of all the containers assigned to the cargo ship into an

attribute called containers. The draft of the ship is dependent on the current cargo of the ship and its

maximum capacity. The ship$$s draft increases linearly as its capacity increases up to its maximum

capacity. The speed of the ship is dependent on its maximum speed and its current draft. The ship$$s

speed decreases linearly as its draft increases up to its maximum draft. The minimum speed of the ship

is $50\%$ of its maximum speed when at its maximum draft.

The following attributes of the container ship class should be calculated from the list of containers:

$$ Cargo $$ The amount of cargo assigned to the container ship in TEUs.

$$ Draft $$ The depth of the container ship given its current cargo and maximum capacity.

$$ Speed $$ The speed of the container ship given its current draft.

Your container ship class must implement methods to get the capacity, draft, and speed for all objects of

the container ship class:

$$ get$\_$cargo$()$ Returns the capacity a TEUs.

$$ get$\_$draft$()$ Returns the draft of the container ship in meters.

$$ get$\_$speed$()$ Returns the speed of the container in knots.

Your container ship class must implement methods to add and remove containers from the ship:

$$ add$\_$container$($ container $)$ Adds the input container to the top of the container ship if the

container does not cause the ship to exceed its maximum capacity.

$$ remove$\_$container$()$ Removes the container at the top of the container ship.

Your container ship class must implement a method to print out the composition of the ship:

$$ print$\_$ship$()$ Prints the following information about the planned cargo of the ship:

o Cargo $$ The amount of cargo that has been filled in TEUs.

o Draft $$ Depth of the containership given its current cargo in meters.

o Speed $$ The speed of the container ship given its current draft in knots.

o Composition $2$ Letter abbreviation for the cargo for each container split across $4$ rows.

$($Containers can be stacked to a maximum height of $4).$ Cargo is loaded bottom up$.$ See
