Usage

Following example is showing how easy you can use this Enum in your code:

from easy_enum import Enum

class TestEnum(Enum):

    # attribute with no description, the name will be 'FIRST_ITEM' and empty string as description
    FIRST_ITEM  = 1

    # attribute with description
    SECOND_ITEM = (2, 'Description for second item')

    # attribute with description and custom string name
    THIRD_ITEM  = (3, 'third', 'Description for third item')

    # attribute with custom string name (the description must be specified as empty string)
    FOURTH_ITEM = (4, 'fourth', '')


# Read attributes value and name
print(TestEnum.SECOND_ITEM)    # 2
print(TestEnum['FIRST_ITEM'])  # 1
print(TestEnum[1])             # 'FIRST_ITEM'
print(TestEnum[3])             # 'third'
print(TestEnum['third'])       # 3

# Use get method with default value if want skip exception
print(TestEnum.get(8))         # None
print(TestEnum.get('eight'))   # None
print(TestEnum.get(8, 'eight')) # 'eight'

# Check if exist attribute with specific value
print(1 in TestEnum)           # True
print(8 in TestEnum)           # False

# Check if exist attribute with specific name
print('first' in TestEnum)     # False
print('third' in TestEnum)     # True

# Get attribute description (as parameter use attribute name or value)
print(TestEnum.desc(1))        # ''
print(TestEnum.desc(2))        # 'Description for second item'
print(TestEnum.desc('third'))  # 'Description for third item'

# Get count of all attributes
print(len(TestEnum))           # 4

# Get list with all attributes name
names = [item[0] for item in TestEnum]
print(names)                   # ['FIRST_ITEM', 'SECOND_ITEM', 'third', 'fourth']

# Get list with all attributes value
values = [item[1] for item in TestEnum]
print(values)                  # [1, 2, 3, 4]

# Read all items
for name, value, desc in TestEnum:
    print('{} = {} ({})'.format(name, value, desc))
