adt-extension
Python abstract data structure (ADT) extension.
Install:
pip install adt-extensionImport:
from adt_extension import Set, SwitchDictExtensions
Currently the package have the ADT extensions:
| Class | Extension of | Description |
|---|---|---|
Set |
set |
Set with element type and validation rule. |
SwitchDict |
dict |
Dictionary with the possibility of behavior of a switch case. |
Set
Set with element type and validation rule for the elements that will be inserted into the set.
Example:
from adt_extension import Set
# A set with only even integers
set_int_even = Set(element_type=int, rule=lambda x: (x % 2 == 0))
# Elements that satisfies the element type and validation rule
set_int_even.update({4, 6})
# Elements that satisfies the element type, but not validation rule
set_int_even.update({5})
# Elements that not satisfies the element type
set_int_even.update({"qwe", True})
print(set_int_even)
# Output:
# Set({4, 6})
# Remove element type
set_int_even.element_type = None
# Remove validation rule
set_int_even.rule = NoneSwitchDict
Dictionary with the possibility to perform a function or return a value when trying to access a nonexistent index in the dictionary class.
Example:
from adt_extension import SwitchDict
# Same behavior of a normal dictionary
switch_dict = SwitchDict({
'Apartament': 125,
'House': 250,
'Condominium': 300,
})
# Add default case
switch_dict.default_case = 999
# List example
properties_list = [
'Apartament',
'House',
'Condominium',
'Treehouse',
'Hotel',
]
# Get values
properties_values = [ switch_dict[ x ] for x in properties_list ]
print(properties_values)
# Output:
# [ 125, 250, 300, 999, 999 ]
# Remove default case, becomes a normal dictionary
switch_dict.default_case = None
