python實現定時顯示天氣預報信息

def get_iciba_everyday_chicken_soup():
    url = 'http://open.iciba.com/dsapi/'
    r = requests.get(url)
    all_content = json.loads(r.text)  # 獲取到json格式的內容，內容很多,json.loads: 將str轉成dict
    English = all_content['content']  # 提取json中的英文雞湯
    Chinese = all_content['note']  # 提取json中的中文雞湯
    everyday_soup = English + '\n' + Chinese  # 合並需要的字符串內容
    return everyday_soup  # 返回結果


# print(get_iciba_everyday_chicken_soup())


def get_weather(city_pinyin):
    # 聲明請求頭，模擬真人操作，防止被反爬蟲發現
    #header需要F12抓取下信息
    header = {
        "User-Agent": "*******"}
    # 通過傳入的城市名拼音參數來拼接出該城市的天氣預報的網頁地址
    #city_pinyin='zhengzhou'
    website = "https://www.tianqi.com/" + city_pinyin + "/"
    req = urllib.request.Request(url=website, headers=header)
    page = urllib.request.urlopen(req)
    html = page.read()
    soup = BeautifulSoup(html.decode("utf-8"), "html.parser")
    # html.parser表示解析使用的解析器
    nodes = soup.find_all('dd')
    tody_weather = [node.text.strip() for node in nodes]  # 定義一個列表，並遍歷nodes
    tody_weather[0] = tody_weather[0][:2]  # 去除多余字符
    # 去除字符串中的空行:
    tianqi = " ".join([s for s in tody_weather if s.strip("\n")])
    print(tianqi)
    return tianqi
    # 返回結果


# 調用封裝號好的函數獲取天氣預報，參數‘zhengzhou’是鄭州的拼音：
# print(get_weather("zhengzhou"))
