Python基于Requestes爬取天气信息及显示

Python基于Requestes爬取天气信息及显示

一、分为以下步骤

1.了解网页；

2.使用 requests 库抓取网站数据；

3.使用 Beautiful Soup 解析网页；

4.清洗和组织数据；

1. 模块的引入

import requests
import tkinter
from tkinter import ttk
import re
import matplotlib.pyplot as plt
from bs4 import BeautifulSoup
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg

2.使用tkinter进行窗口化及显示

def UI(prcouse_dict,stert_url,url_list,city_list):
    prcouse_lsit = list(prcouse_dict.keys())
    ui =tkinter.Tk()
    ui.title("天气信息")
    ui.geometry("750x800")

    variable1 = tkinter.StringVar()
    listbox1 = ttk.Combobox(ui,width=12,textvariable = variable1)
    listbox1["values"]=prcouse_lsit
    listbox1.current(0)
    listbox1.place(relx = 0.1,rely = 0.05)

    button1 = tkinter.Button(ui,text="切换",command=lambda: getUrl_city(stert_url, url_list, city_list, variable1, prcouse_dict,listbox2,text1))
    button1.place(relx=0.3, rely=0.05)

    variable2 = tkinter.StringVar()
    listbox2 = ttk.Combobox(ui,width=12,textvariable = variable2)
    getUrl_city(stert_url, url_list, city_list, variable1, prcouse_dict,listbox2,ui)
    listbox2["values"] = city_list
    listbox2.current(0)
    listbox2.place(relx = 0.4,rely = 0.05)

    button2 = tkinter.Button(ui,text = "查看",command = lambda:getMeaage_weak(listbox2,city_list,url_list,text1,text2))
    button2.place(relx = 0.6,rely = 0.05
