コードブロックとハイライトの書式は以下の通りです：
```python
elif a[1] in ["3", "4"]:
```
この単純化は、条件を読みやすく変更しやすくすることで、より多くの値を扱うときに役立ちます：
```python
a_value = ["3", "4", "7", "a", "m", "t", "q", "z", "?"]

elif a[1] in a_value:
```
Sure. Here is the format with the code block and highlighting:
```python
elif a[1] in ["3", "4"]:
```
This simplification can be useful when dealing with a lot more values, by making the condition easier to read and change:
```python
a_value = ["3", "4", "7", "a", "m", "t", "q", "z", "?"]

elif a[1] in a_value:
```
