# Python Import Style
## Avoid Importing Classes Directly
Do not import classes directly from modules. Instead, import the module and refer to the class as a member of the module.
**Exception**: Members of the `typing` module (e.g., `List`, `Optional`, `Dict`, `Any`) may be imported directly.
### ❌ BAD
```python
from my_module import MyClass
from other_module import OtherClass
obj = MyClass()
```
### ✅ GOOD
```python
import my_module
import other_module
from typing import List, Optional
obj = my_module.MyClass()
def func(args: List[str]) -> Optional[int]:
pass
```
This makes it clearer where classes come from and avoids naming conflicts, while keeping type hints concise.
## Inline Single-Use Variables
If a variable is used only once and its name doesn't provide significant documentation value or aid debugging, inline it.
### ❌ BAD
```python
job_name = f"my-job-{timestamp}"
client.create_job(name=job_name)
```
### ✅ GOOD
```python
client.create_job(name=f"my-job-{timestamp}")
```
