OpenWeatherMapとPySimpleGUIでお天気表示GUIを作る

Posted at

はじめに

OpenWeatherMapでデータを取得してPySimpleGUIで天気を表示しました。

OpenWeatherMapについて

実装コードにはOpenWeatherMapのAPIを利用しています。
利用するにはAPIkeyの取得が必要です。
取得方法については以下にまとめられています。

実装コード

API部(OpenWeatherMap部)

class MyWeather:
    API_Endpoint = "http://api.openweathermap.org/data/2.5/forecast"
    API_Key = "あなたのkeyを入力"
    location = "Osaka"
    query = {"q": location, "APPID": API_Key, "lang": "ja"}
    data = requests.get(API_Endpoint, params=query).json()

classの先頭でAPIに渡す情報を作っています。
queryの内容やAPIの返答内容(dataの中身)はOpenWeatherMapのFAQみたいなところに書いてあります。
参考にした記事:APIの仕組みが分かる・使いこなせる人材になれる記事（Pythonコード付き）

描画部(PySimpleGUI部)

    def drawScreen(self):
        sg.theme("Python")#GUIの配色

        title = [
            [sg.Text(str(self.getTime(0))+'～' +
                     str(self.getTime(self.WEATHER_LENGTH-1)+'の'+self.location+'の'+'天気'), font=('メイリオ', 20))]
        ]
        titleFrame = sg.Frame(
            '', [[sg.Column(title, justification='c')]], size=(self.WEATHER_LENGTH*150, 100))


        timeText = [[]]
        timeFrame = [[]]
        timeFrameBig = [[]]
        for i in range(self.WEATHER_LENGTH):
            time = str(self.getTime(i).split(' ', 1)[1])
            time = time.split(':', 1)[0]
            timeText = [sg.Column
                        ([[sg.Text(time+'時', font=('メイリオ', 30))]], justification='c')]
            timeFrame[0].extend(
                [sg.Frame('', [timeText], size=(150, 100))])
        timeFrameBig = [[sg.Frame('', [timeFrame[0]])]]


        icon = [[]]
        iconFrame = [[]]
        iconFrameBig = [[]]
        for i in range(self.WEATHER_LENGTH):
            icon = [
                sg.Column([[sg.Image(self.getWeather(i))]], justification='c')]
            iconFrame[0].extend(
                [sg.Frame('', [icon], size=(150, 120))])
        iconFrameBig = [[sg.Frame('', [iconFrame[0]])]]


        layout = [[titleFrame], [timeFrameBig], [iconFrameBig]]
        window = sg.Window("お天気", layout, resizable=True)
        while True:
            event, values = window.read()
            if event == sg.WIN_CLOSED:
                break

        window.close()

描画部分です。

        layout = [[titleFrame], [timeFrameBig], [iconFrameBig]]
        window = sg.Window("お天気", layout, resizable=True)
        while True:
            event, values = window.read()
            if event == sg.WIN_CLOSED:
                break

layout内にGUIのレイアウトを記述します。レイアウトについては以下の記事が参考になると思います。

PySimpleGUIのレイアウトの設定方法

タイトル部

   def drawScreen(self):
        sg.theme("Python")#GUIの配色

        title = [
            [sg.Text(str(self.getTime(0))+'～' + #self.getTime(i)の返り値→ 19XX-YY-ZZ xx:yy:zz
                     str(self.getTime(self.WEATHER_LENGTH-1)+'の'+self.location+'の'+'天気'), font=('メイリオ', 20))]
        ]
        titleFrame = sg.Frame(
            '', [[sg.Column(title, justification='c')]], size=(self.WEATHER_LENGTH*150, 100))

赤枠の部分です。sg.Text単体では文章を中央揃えにできなさそうなので、sg.Columnを介して中央揃えにしています。

時間部


        timeText = [[]]
        timeFrame = [[]]
        timeFrameBig = [[]]
        for i in range(self.WEATHER_LENGTH):#self.getTime(i)の返り値→ 19XX-YY-ZZ xx:yy:zz
            time = str(self.getTime(i).split(' ', 1)[1])#xx:yy:zz
            time = time.split(':', 1)[0]#xx
            timeText = [sg.Column
                        ([[sg.Text(time+'時', font=('メイリオ', 30))]], justification='c')]
            timeFrame[0].extend(
                [sg.Frame('', [timeText], size=(150, 100))])
        timeFrameBig = [[sg.Frame('', [timeFrame[0]])]]

image.png
赤枠の部分です。リストの入れ子構造を間違えてエラーが頻発しました。
ここもsg.Columnで中央揃えにしています。

アイコン部

        icon = [[]]
        iconFrame = [[]]
        iconFrameBig = [[]]
        for i in range(self.WEATHER_LENGTH):
            icon = [
                sg.Column([[sg.Image(self.getWeather(i))]], justification='c')]#self.getWeatherの返り値は画像のパス
            iconFrame[0].extend(
                [sg.Frame('', [icon], size=(150, 120))])
        iconFrameBig = [[sg.Frame('', [iconFrame[0]])]]

image.png
赤枠の部分です。self.getWeather(i)は画像のパスを返します。

getWeather

    def getWeather(self, num):  # 天気アイコンのパスを返す

        sunnyImage = "weather/icon/sunny_icon.png"
        fewCloudsImage = "weather/icon/fewClouds_icon.png"
        brokenCloudsImage = "weather/icon/brokenClouds_icon.png"
        cloudyImage = "weather/icon/cloudy_icon.png"
        rainyImgae = "weather/icon/rainy_icon.png"
        snowImage = "weather/icon/snow_icon.png"
        thunderImage = "weather/icon/thunder_icon.png"
        errorImage = "weather/icon/error_icon.png"

        weather = self.data["list"][num]["weather"]
        icon = weather[0]["icon"]
        if icon == "01n" or icon == "01d":
            return sunnyImage
        elif icon == "02d" or icon == "02n":
            return fewCloudsImage
        elif icon == "03d" or icon == "03n":
            return cloudyImage
        elif icon == "04d" or icon == "04n":
            return brokenCloudsImage
        elif icon == "09d" or icon == "09n":
            return rainyImgae
        elif icon == "10d" or icon == "10n":
            return rainyImgae
        elif icon == "11d" or icon == "11n":
            return thunderImage
        elif icon == "13d" or icon == "13n":
            return snowImage
        else:
            return errorImage

天気アイコンはicoon-mono 様のものをお借りしました。
また、OpenWetherMapに詳細なアイコンのIDがあります。
