python - 具有多个条件的字典的逆模糊匹配

Question

我正在尝试在 python 字典上使用多个条件进行逆模糊选择，但无法实现。

我有一本包含天气信息的字典:

{'time': '2020-01-21',
 'summary': 'Rain and dangerously windy throughout the day.',
 'icon': 'rain',
 'sunriseTime': 1579590780,
 'sunsetTime': 1579625640,
 'moonPhase': 0.9,
 'precipIntensity': 4.0669,
 'precipIntensityMax': 6.6666,
 'precipIntensityMaxTime': 1579640520,
 'precipProbability': 1,
 'precipType': 'rain',
 'temperatureHigh': 13.39,
 'temperatureHighTime': 1579608240,
 'temperatureLow': 11.49,
 'temperatureLowTime': 1579645500,
 'apparentTemperatureHigh': 13.11,
 'apparentTemperatureHighTime': 1579608240,
 'apparentTemperatureLow': 11.76,
 'apparentTemperatureLowTime': 1579645500,
 'dewPoint': 9.58,
 'humidity': 0.88,
 'pressure': 1024.8,
 'windSpeed': 14.23,
 'windGust': 23.47,
 'windGustTime': 1579628880,
 'windBearing': 72,
 'cloudCover': 0.99,
 'uvIndex': 1,
 'uvIndexTime': 1579608060,
 'visibility': 6.288,
 'ozone': 406.5,
 'temperatureMin': 8.41,
 'temperatureMinTime': 1579569780,
 'temperatureMax': 13.82,
 'temperatureMaxTime': 1579639560,
 'apparentTemperatureMin': 3.78,
 'apparentTemperatureMinTime': 1579569360,
 'apparentTemperatureMax': 13.54,
 'apparentTemperatureMaxTime': 1579639560}

我想删除文本中带有“Time”、“High”或“Low”的所有键。

以下代码为我提供了我想要删除的所有键:

{k:v for (k,v) in forecast_dict[0].items() for x in ["Time", "High", "Low"] if x in k}

输出:

{'sunriseTime': 1579590780,
 'sunsetTime': 1579625640,
 'precipIntensityMaxTime': 1579640520,
 'temperatureHigh': 13.39,
 'temperatureHighTime': 1579608240,
 'temperatureLow': 11.49,
 'temperatureLowTime': 1579645500,
 'apparentTemperatureHigh': 13.11,
 'apparentTemperatureHighTime': 1579608240,
 'apparentTemperatureLow': 11.76,
 'apparentTemperatureLowTime': 1579645500,
 'windGustTime': 1579628880,
 'uvIndexTime': 1579608060,
 'temperatureMinTime': 1579569780,
 'temperatureMaxTime': 1579639560,
 'apparentTemperatureMinTime': 1579569360,
 'apparentTemperatureMaxTime': 1579639560}

当我尝试使用以下命令进行反向选择时:

{k:v for (k,v) in forecast_dict[0].items() for x in ["Time", "High", "Low"] if x not in k}

我取回了整本字典以及所有条目。我认为问题出在列表解包上，但是如果它适用于直接过滤，那么它不应该适用于反向过滤吗？

Answer 1

这就是你所追求的吗？使用 any() 和生成器:

>>> {k:v for k, v in forecast_dict[0].items() if not any(x in k for x in["Time", "High", "Low"])}
{'time': '2020-01-21',
 'summary': 'Rain and dangerously windy throughout the day.',
 'icon': 'rain',
 'moonPhase': 0.9,
 'precipIntensity': 4.0669,
 'precipIntensityMax': 6.6666,
 'precipProbability': 1,
 'precipType': 'rain',
 'dewPoint': 9.58,
 'humidity': 0.88,
 'pressure': 1024.8,
 'windSpeed': 14.23,
 'windGust': 23.47,
 'windBearing': 72,
 'cloudCover': 0.99,
 'uvIndex': 1,
 'visibility': 6.288,
 'ozone': 406.5,
 'temperatureMin': 8.41,
 'temperatureMax': 13.82,
 'apparentTemperatureMin': 3.78,
 'apparentTemperatureMax': 13.54}
