清單可以包含多種資料型別，也能包含清單本身。
範例：用巢狀清單描述月份及其消費者物價指數（CPI）
```
  cpi = [['Jan', 'Feb', 'Mar'], [238.11, 237.81, 238.91]]
```

擷取巢狀清單

months = ['Jan', 'Feb', 'Mar']
print(months[1])

'Feb'

cpi = [['Jan', 'Feb', 'Mar'], [238.11, 237.81, 238.91]]
print(cpi[1])

[238.11, 237.81, 238.91]

要如何擷取特定的物價指數？

cpi = [['Jan', 'Feb', 'Mar'], [238.11, 237.81, 238.91]]
print(cpi[1])

[238.11, 237.81, 238.91]

print(cpi[1][0])

238.11
