Enums

Enums are kind of hacky in python. See the below example.

import enum

# Enums are kind of hacky, use a class
class Animal(enum.Enum):
    dog = 1
    cat = 2
    lion = 3

# printing enum member as string 
print(f"The string representation of enum member is : {Animal.dog}") # Animal.dog
  
# printing enum member as repr 
print(f"The repr representation of enum member is : {repr(Animal.dog)}") # <Animal.dog: 1>

# printing the type of enum member using type() 
print ("The type of enum member is : ",end ="") 
print (type(Animal.dog)) # <enum 'Animal'>
  
# printing name of enum member using "name" keyword 
print ("The name of enum member is : ",end ="") 
print (Animal.dog.name) # dog

# Accessing enum member using value  
print ("The enum member associated with value 2 is : ",end="") 
print (Animal(2)) # Animal.cat
  
# Accessing enum member using name   
print ("The enum member associated with name lion is : ",end="") 
print (Animal['lion']) # Animal.lion

# Assigning enum member  
mem = Animal.dog 
  
# Displaying value  
print ("The value associated with dog is : ",end="") 
print (mem.value) # 1
  
# Displaying name   
print ("The name associated with dog is : ",end="") 
print (mem.name) # dog

# Comparison using "is"  
if Animal.dog is Animal.cat: 
       print ("Dog and cat are same animals") 
else : print ("Dog and cat are different animals")  
  
# Comparison using "!=" 
if Animal.lion != Animal.cat: 
       print ("Lions and cat are different") 
else : print ("Lions and cat are same") 

# Iterable
for a in (Animal):
    print(a)
