Но если вам любопытен именно этот пример и всё ещё интересно, вот немного подробностей.

#### Строка и `value.startswith()` { #string-with-value-startswith }

Заметили? Метод строки `value.startswith()` может принимать кортеж — тогда будет проверено каждое значение из кортежа:

{* ../../docs_src/query_params_str_validations/tutorial015_an_py310.py ln[16:19] hl[17] *}

  @Override
  public String toString() {
    long nanos = elapsedNanos();

    TimeUnit unit = chooseUnit(nanos);
    double value = (double) nanos / NANOSECONDS.convert(1, unit);

    // Too bad this functionality is not exposed as a regular method call
    return Platform.formatCompact4Digits(value) + " " + abbreviate(unit);
  }

  private static TimeUnit chooseUnit(long nanos) {
    if (DAYS.convert(nanos, NANOSECONDS) > 0) {

            return map;
          }

          @Override
          public Collection<Boolean> values() {
            return new StandardValues();
          }
        };
    callAllPublicMethods(new TypeToken<Collection<Boolean>>() {}, forward.values());

    // These are the methods specified by StandardValues
    verify(map, atLeast(0)).clear();

}
```

#### Unpacking a `dict` { #unpacking-a-dict }

If we take a `dict` like `user_dict` and pass it to a function (or class) with `**user_dict`, Python will "unpack" it. It will pass the keys and values of the `user_dict` directly as key-value arguments.

So, continuing with the `user_dict` from above, writing:

```Python
UserInDB(**user_dict)
```

would result in something equivalent to:

```Python
UserInDB(

        }

            this.setupWireFormatReturn = value;

            this.parametersWireFormatReturn = value;
        }

            this.dataWireFormatReturn = value;

        BigInteger xValue = new BigInteger(x, 16);
        long xLong = xValue.longValue(); // signed
        assertThat(UnsignedLongs.toString(xLong, base)).isEqualTo(xValue.toString(base));
      }
    }
  }
