# Python Enums

An enumeration is a set of symbolic names (members) bound to unique, constant values. Within an enumeration, the members can be compared by identity, and the enumeration itself can be iterated over.

## Importing the Module

```python
from enum import Enum
```

## Creating an Enum

```python
class Color(Enum):
    RED = 1
    GREEN = 2
    BLUE = 3
```

## Accessing Members

```python
print(Color.RED)       # Color.RED
print(Color.RED.name)  # RED
print(Color.RED.value) # 1
```

## Auto Values

Using `auto()` allows you to replace the value with an appropriate value automatically.

```python
from enum import Enum, auto

class Color(Enum):
    RED = auto()
    GREEN = auto()
    BLUE = auto()
```

## Iterating

```python
for color in Color:
    print(color)
```

## Comparisons

```python
if Color.RED is Color.RED:
    print("Identity comparison works")
```
