Production Subpackage

fruit_info.py

Module fruit_info defines a hierarchy of fruit classes (subclasses: Apple, Cherry, Peach) that represent various fruits planted in the orchard, and methods to store, modify and manage their information.

Class: Fruit

Class Fruit represents an abstract base class for various fruits planted in an orchard. It includes basic information about fruit, such as fruit variety, size, sweet, sour, taste, price, use, etc

• variety: The variety of the fruit.

• size: The size of the fruit. e.g.: medium, big

• sweet: The sweetness of the fruit e.g. very sweet

• sour: The sourness of the fruit. e.g. less sour

• taste: The taste of the fruit, e.g., 'crunchy'.

• price: The price of the fruit. e.g. 2.99

• use: The intended use of the fruit. e.g.: "pie"

Method of Fruit:

• describe() -> string:

Returns a brief statement describing the fruit, including size, sourness, sweetness, taste, and use.

• get_price() -> float:

Returns the price of the fruit.

• set_price(price):

Sets the price of the fruit.

Abstract Methods in Fruit:

• get_type_num() -> int:

Abstract method, returns the type number of the fruit.

• get_available_season(date):

Abstract method, returns the available season of the fruit for the given date.

• get_type():

Abstract method, returns the type of fruit.

Those three abstract methods will be concretely implemented in subclasses: Apple, Cherry and Peach

Subclasses of Fruit:

• Apple:

Represents an Apple, a specific subclass of Fruit.

- type_num: The unique type number assigned to all instances of Apple.

- type: The type of fruit, always set to "apple".

- season_dict: A dictionary correlating the seasons with the variety of apples allowed for cultivation in the orchard.

• Cherry:

Represents a Cherry, a specific subclass of Fruit.

- type_num: The unique type number assigned to all instances of Cherry.

- type: The type of fruit, always set to "cherry".

- season_dict: A dictionary correlating the seasons with the variety of cherries allowed for cultivation in the orchard.

• Peach:

Represents a Peach, a specific subclass of Fruit.

- type_num (int): The unique type number assigned to all instances of Peach. always set to 1

- type (str): The type of fruit, always set to "peach".

- season_dict (dict): A dictionary correlating the seasons with the variety of peaches

  allowed for cultivation in the orchard.

Methods in subclasses:

• get_type_num() -> int:

Returns the type number of apple/cherry/peach.

• get_available_season(date):

Returns True if the Peach variety is available in the given date's season, False otherwise. Meanwhile, print at the given season, the Peach variety is in season, out of season, or season has not arrived yet.

Methods:

• fruit_available_check(date, fruit) -> bool:

Check if the input fruit is in season for the given date.

• available_season_fruit(date,fruit_list):

Check which fruits are in season for the given date and return a list of fruits.

• fruit_class_load(file_path) -> list:

• get_fruit(type_num, variety, fruits_list) -> Fruit:

Retrieves a specific fruit instance based on type number and variety.

• fruit_information_store(fruit_list, csv_file_path):

Store fruit information in a CSV file for later retrieval.

• fruit_class_load(fruit_file):

Load fruit information from a file and return a list of Fruit instances.

• get_fruit(fruit_type_num, variety, fruit_list) -> Fruit:

Retrieve a unique fruit class based on type number and variety from the given fruit list.

• add_fruit(fruit_type_num, variety, size, sweet, sour, taste, price, use, fruit_list, fruit_file):

Add a new type of fruit record to the list of fruits. The new fruit should not have same type_num and variety with existed fruits.

• remove_fruit(fruit_type_num, variety, fruit_file):

Remove a fruit record from the list of fruits based on the type number and variety.

Help method: Store data in a CSV file.

• file_load(file_path):

Help method: Load data from a file. Returns a list of file rows.

plantation.py

Module plantations contains class and functions related to fruit cultivation regioins. The whole plantation is divided into several regions for different fruit and different use (customer picking/market wholesale.) There is a class region record the basic information and status of regions. Methods including area calculations, region summary report, and data storeage using Dataframes, etc.

Class: Region

Represents a region with specific fruit cultivation information, including region ID, fruit type number, variety, area, and area type.

• regionId (int): The unique identifier for the region.

• fruit_type_num (int): The type number of the fruit cultivated in the region.

• variety (str): The variety of the fruit cultivated in the region.

Methods about Regions:

• get_area_type():

Returns the area type of the region.

• set_area_type(areaType):

Sets the area type of the region. There is only two valid area type: "pick" and "market"

• get_area():

Returns the area of the region.

• get_fruit(fruit_list):

Retrieves the specific fruit instance for the region.

• region_display(fruit_list):

Displays information about the region and the cultivated fruit.

Methods:

• area_amount_variety(plantation_list, fruit_type_num, fruit_variety):

Get the total planting area for a specific fruit type and variety. Return as a pivot dataframe.

• fruit_index_list(plantation_list, fruit_type_num, fruit_variety):

Help Method: Get lists of region IDs for a specific fruit type and variety based on area type.

• add_region(regionId, fruit_type_num, variety, area, areaType, fruit_list, region_list, planatation_file):

Add a new region to the list of regions. This method works for plantation initialization. Since the area of orchard is constant, the number of regions is limited. So this method will only call at the start of main.

Management Subpackage

inventory.py

Handles inventory, remaining production capacity management and simple visualization.

Datafiles:

Here are three CSV files: "inventory.csv", "remaining_productivity.csv", and "extra_productivity.csv".
