また、何らかの方法で例外を使用することもできますが、**FastAPI** から同じデフォルトの例外ハンドラを使用することもできます。

デフォルトの例外ハンドラを`fastapi.exception_handlers`からインポートして再利用することができます:

{* ../../docs_src/handling_errors/tutorial006.py hl[2,3,4,5,15,21] *}

この例では、非常に表現力のあるメッセージでエラーを`print`しています。

```Python
with open("./somefile.txt") as f:
    contents = f.read()
    print(contents)
```

내부적으로 `open("./somefile.txt")` 는 "컨텍스트 관리자(Context Manager)"라고 불리는 객체를 생성합니다.

`with` 블록이 끝나면, 예외가 발생했더라도 파일을 닫도록 보장합니다.

Omdat de editor de types van de variabelen kent, krijgt u niet alleen aanvulling, maar ook controles op fouten:

Nu weet je hoe je het moet oplossen, converteer `age` naar een string met `str(age)`:

## Types declareren

Je hebt net de belangrijkste plek om type hints te declareren gezien. Namelijk als functieparameters.

    // clear absent
    assertFalse(segment.clearValueForTesting(key, hash, valueRef));

    segment.setTableEntryForTesting(0, entry);
    // don't increment count; this is used during computation
    assertTrue(segment.clearValueForTesting(key, hash, valueRef));
    // no notification sent with clearValue
    assertEquals(0, segment.count);
    assertNull(table.get(0));

      }

      return new BloomFilter<>(dataArray, numHashFunctions, funnel, strategy);
    } catch (IOException e) {
      throw e;
    } catch (Exception e) { // sneaky checked exception
      String message =
          "Unable to deserialize BloomFilter from InputStream."
              + " strategyOrdinal: "
              + strategyOrdinal
              + " numHashFunctions: "
              + numHashFunctions

    // clear absent
    assertFalse(segment.clearValueForTesting(key, hash, valueRef));

    segment.setTableEntryForTesting(0, entry);
    // don't increment count; this is used during computation
    assertTrue(segment.clearValueForTesting(key, hash, valueRef));
    // no notification sent with clearValue
    assertEquals(0, segment.count);
    assertNull(table.get(0));
