# import enum

**[import enum](https://docs.python.org/3/library/enum.html)** is a Python import that defines enumerations: fixed sets of symbolic names. Use `Enum` to create cleaner code than magic strings.

## Example

```python
# Python
# description: define and use enumerations

from enum import Enum, auto

class Status(Enum):
    PENDING = "pending"
    ACTIVE = "active"
    COMPLETED = "completed"

# Access enum members
print(Status.PENDING)  # Status.PENDING
print(Status.PENDING.value)  # pending

# Use in code
current_status = Status.ACTIVE
if current_status == Status.ACTIVE:
    print("Task is running")

# Auto-assign values
class Color(Enum):
    RED = auto()      # 1
    GREEN = auto()    # 2
    BLUE = auto()     # 3

# Iterate over enum members
for status in Status:
    print(status.name, status.value)

# Get member by value
status = Status("active")
print(status)  # Status.ACTIVE
```

## Common classes

- `Enum`: base class for enumerations
- `enum.auto()`: auto-assign integer values
- `member.name`: name of enum member
- `member.value`: value of enum member
- `Enum["ACTIVE"]`: get by name
- `Enum("active")`: get by value
