Python can also be a caring butler-daily report countdown to postgraduate entrance examination, weather conditions, and "nutritious chicken soup"

I. Introduction

For the postgraduate entrance examination, are you still counting how many days there are? Regarding the weather, do you still check the weather forecast every day? Do you need to read some inspirational words every day to push yourself forward?
Python can combine the above three into one to help you easily realize your daily life!
Please see the detailed explanation below.

Second, the library that needs to be imported

import requests
from lxml import etree
import json
import cv2
import pyttsx3
import datetime

Three, analysis

1. Countdown to postgraduate entrance examination

For the countdown, I used the datetimelibrary to get the real-time time, and split the year, month, and date, set the graduate exam time by myself, and then subtract the two. The function code is as follows:

# 获取日期和倒计时
def get_time():
    a = datetime.datetime.now()  # 实施时间
    y = str(a.year)
    m = str(a.month)
    d = str(a.day)  # 转换为字符串，便于打印
    time = y + '年' + m + '月' + d + '日' + '\n'
    b = datetime.datetime(2021, 12, 25)  # 自己设置的研究生考试时间
    count_down = (b - a).days  # 考研倒计时
    return time, count_down

2. Weather conditions

Take Nantong as an example, the link to crawl the web page is: http://www.weather.com.cn/weather/101190501.shtml
(If you need to switch to another city , change the above link 101190501to the city that needs to be switched ID

is enough . After right-clicking on the above link page to open the check page, the following figure is a detailed step diagram) To obtain the content, I wrote an article before, which is more detailed.
"Python crawls weather forecast data and realizes data visualization"

Implementation code:

def get_weather():
    url = 'http://www.weather.com.cn/weather/101190501.shtml'
    response = requests.get(url)
    response.encoding = 'utf-8'
    response = response.text  # 获取页面
    html = etree.HTML(response)
    day_weather = '天气状况：' + html.xpath('//*[@id="7d"]/ul/li[1]/p[1]/text()')[0] + '\n'  # 获取天气，白天的天气
    high = html.xpath('//*[@id="7d"]/ul/li[1]/p[2]/span/text()')
    low = html.xpath('//*[@id="7d"]/ul/li[1]/p[2]/i/text()')  # 获取对应的两个温度
    # 因为页面在晚上会有小变化，所以使用条件语句，来排除因变化引起的bug
    if high == []:
        day_temperature = '室外温度：' + low[0] + '\n'
    else:
        day_temperature = '室外温度：' + low[0].replace('℃', '') + '~' + high[0] + '℃\n'  # 获取温度
    # 获取两个风向
    wind_1 = html.xpath('//*[@id="7d"]/ul/li[1]/p[3]/em/span[1]/@title')
    wind_2 = html.xpath('//*[@id="7d"]/ul/li[1]/p[3]/em/span[2]/@title')
    # 因为有时候，会出现两个风向是同一个风向的情况，所以使用条件语句排除
    if wind_2 == []:
        wind = wind_1[0] + '\n'
    elif wind_1[0] == wind_2[0]:
        wind = wind_1[0] + '\n'
    else:
        wind = wind_1[0] + '转' + wind_2[0] + '\n'
    # 因为风级有时候会出现“<"，语音的时候会认为是爱心符号，所以使用替换，改为文字”低于“
    wind_3 = html.xpath('//*[@id="7d"]/ul/li[1]/p[3]/i/text()')[0].replace('<', '低于').replace('>', '高于')
    day_wind = '风向情况：' + wind + wind_3 + '\n'  # 获取风向及风级
    return day_weather, day_temperature, day_wind

3. Nutritious chicken soup

For fun and to practice listening by the way, I crawled the Chinese and English sentence of the day from "iCIBA", and crawled the link of the picture for display (the picture will not be saved , and the picture will disappear after the code runs)
Because there are interfaces on the Internet, we directly use the crawling between interfaces.
code show as below:

def get_content():
    url = 'http://open.iciba.com/dsapi/'  # 网上找的API
    response = requests.get(url=url)
    json_s = json.loads(response.text)
    jitang = json_s.get("content") + '\n'  # 每日鸡汤
    translation = json_s.get("note") + '\n'  # 中文翻译
    image_url = json_s.get("fenxiang_img")  # 图片链接
    return jitang, translation, image_url

Fourth, the complete code

In the main function, the pyttsx3library is used to realize the voice broadcast function and the cv2picture display function is used.
code show as below:
