前幾天弄了台北市分區的表格，發現橫向資料太多，需要改滿多的...，就改變一下，先做行政各區的天氣預報
會這樣決定是因為想先把小部份完成，看一下效果，再做個全台北市的天氣預報。
各區天氣預報要呈現項目
整理資料局部程式碼，這邊將需要的欄位（溫度、體感溫度...），都用一個list處理
dataDictList = []
locations = resJson["records"]["locations"][0]["location"]
for index, location in enumerate(locations):
weatherElements = location["weatherElement"]
temperatureDictList = [] # 溫度
aTemperatureDictList = [] # 體感溫度
pop6HDictList = [] # 降雨機率 6hr
wxDictList = [] # 天氣現象
ciDictList = [] # 舒適度
for weatherElement in weatherElements:
# 溫度
if weatherElement["elementName"] == "T":
timeDicts = weatherElement["time"]
for timeDict in timeDicts:
temperatureDictList.append({
"dataTime": timeDict["dataTime"],
"value": timeDict["elementValue"][0]["value"],
})
# 體感溫度
if weatherElement["elementName"] == "AT":
timeDicts = weatherElement["time"]
for timeDict in timeDicts:
aTemperatureDictList.append({
"dataTime": timeDict["dataTime"],
"value": timeDict["elementValue"][0]["value"],
})
# 降雨機率 百分比
if weatherElement["elementName"] == "PoP6h":
timeDicts = weatherElement["time"]
for timeDict in timeDicts:
pop6HDictList.append({
"startTime": timeDict["startTime"],
"endTime": timeDict["endTime"],
"value": timeDict["elementValue"][0]["value"],
})
# 天氣現象 Text
if weatherElement["elementName"] == "Wx":
timeDicts = weatherElement["time"]
for timeDict in timeDicts:
wxDictList.append({
"startTime": timeDict["startTime"],
"endTime": timeDict["endTime"],
"value": timeDict["elementValue"][0]["value"],
})
# 舒適度指數
if weatherElement["elementName"] == "CI":
timeDicts = weatherElement["time"]
for timeDict in timeDicts:
ciDictList.append({
"dataTime": timeDict["dataTime"],
"valueNum": timeDict["elementValue"][0]["value"],
"value": timeDict["elementValue"][1]["value"],
})
tempDict = {
"locationName": location["locationName"],
"temperatureDictList": temperatureDictList,
"aTemperatureDictList": aTemperatureDictList,
"pop6HDictList": pop6HDictList,
"wxDictList": wxDictList,
"ciDictList": ciDictList,
}
dataDictList.append(tempDict)
這邊字體有多定義了標題一、標題二，字體大小不一樣
以各行政區一頁，跑迴圈呼叫 表格func，專門寫各區的表格，因為降雨機率為六個小時，所以會用到合併欄位
('SPAN', (3, 1), (3, 2)), 後面參數是從哪裡到哪裡。

結果圖 總共有12頁，隨便拿兩頁看一下，看起來還不錯，就清楚顯示所有資料欄位。
