[python] 开发城市天气预报

python开发城市天气预报

两年在学习python中,稍微学习了一点爬虫技术，并且作者一直喜欢开发游戏，然后就有学习了pygame框架，作者奇思妙想让两者集合一下开发一个天气预报，那么这就行动。
先运行编译后的截图：

有一种星空颗粒的感觉对吧。

开始代码：

# -*- coding:utf-8 -*-
from urllib import request
from bs4 import BeautifulSoup
import os,sys,pygame
from pygame.locals import *
from random import randint
pygame.init()

导入我们所有的包

不会下载的，进入cmd控制台输入pip install 名

然后写一个主函数

def main:
	pass

if __name__ == '__main__':
	main()

开始写入内存

error = 0
	try:
		response = request.urlopen('http://www.weather.com.cn/weather/101250101.shtml')
		html = response.read()
		soup = BeautifulSoup(html,'html.parser',from_encoding='gbk')
	#*********************************************************
		#天气地名存入数据
		plasename = soup.find_all('div',class_="crumbs fl")[0]
		plase1=plasename.find_all('a')
		plase2=plasename.find_all('span')
		plase_info = []
		p_ind = 0
		for p1 in plase1:
			plase_info.append(plase1[p_ind].get_text())
			plase_info.append(plase2[p_ind].get_text())
			p_ind += 1
		plase_info.append(plase2[p_ind].get_text())
		#天气地名存入数据
		#本周的天气信息存入数据
		itclass = soup.find_all(class_='t clearfix')[0]
		itli=itclass.find_all('li')
		info_data = []
		for li in itli:
			inf1 = li.find_all('h1')[0].get_text()
			inf2 = li.find_all('p',class_='wea')[0].get_text()
			inf3 = li.find_all('p',class_='tem')[0].get_text().strip('\n')
			inf4 = li.find_all('p',class_='win')[0].get_text().strip('\n')
			info_data.append([inf1,inf2,inf3,inf4])
		#本周的天气信息存入数据
	except:
		error = 1

窗口和爬虫预备

#*********************************************************
	#********************
	#plase_info  地名信息
	#info_data   天气信息
	#使用pygame显示天气信息
	#********************
	screen = pygame.display.set_mode((602, 462))
	caption = pygame.display.set_caption('天气预报')
	#font = pygame.font.Font('./m.ttf',25)
	#font2 = pygame.font.Font('./m.ttf',16)
	font = pygame.sysfont.SysFont('microsoft yahei', 25)
	font2 = pygame.sysfont.SysFont('microsoft yahei', 16)
	fonte = pygame.sysfont.SysFont('microsoft yahei', 40)
	fonte = fonte.render("网络没有连接",True, (100,200,255))
	wp = 200
	hp = 140
	pos = []
	color = (100,100,255)
	flag = 0
	ppxy = [0,0]

	timer = 0
	wh = [602, 462]
	acpos = [[randint(150,903),randint(462, 562),randint(1, 2)]]

	pygame.init()

事件循环

while True:
		screen.fill([255,255,255])
		for event in pygame.event.get():
			if event.type == QUIT:
				sys.exit()
			if event.type == MOUSEBUTTONDOWN:
				mpos = event.pos
				flag = 0
				for p in pos:
					if mpos[0]>p[0] and mpos[0]<p[0]+wp:
						if mpos[1]>p[1] and mpos[1]<p[1]+hp:
							flag = 1
							ppxy = p
							break

最后画出地名信息和天气信息然后一个动态颗粒动画。

#-------------------------画地名-----------------------
		if error:
			screen.blit(fonte,(wh[0]/2-fonte.get_width()/2,wh[1]/2-fonte.get_width()/2))
		else:
			index = 0
			for pl in plase_info:
				pf = font.render('%s'%pl, True, (100,200,100))
				screen.blit(pf,(150+60*index,0))
				index += 1
			pygame.draw.line(screen,(255,0,128), (0,35), (640,35),5)
			#-------------------------画地名-----------------------
			#-------------------------画天气信息-----------------------
			for i in range(3):
				for j in range(3):
					if j == 0:
						w = 0
					if j == 1:
						w = 201
					if j == 2:
						w =402

					if i == 0:
						h = 40
					if i == 1:
						h = 181
					if i == 2:
						h = 322
					pygame.draw.rect(screen,color,(w,h,wp,hp))
					pos.append([w,h])
			if flag:
				pygame.draw.rect(screen,(255,0,128),(ppxy[0],ppxy[1],wp,hp))
			
			index = 0
			for info in info_data:
				ind = 0
				for io in info:
					inf = font2.render('%s'%io, True, (255,255,128))
					screen.blit(inf,(100-inf.get_width()/2+pos[index][0],20+pos[index][1]+23*ind))
					ind += 1
				index += 1
			#-------------------------画天气信息-----------------------

			timer += 1
			if timer >= 2:
				acpos.append([randint(150,903),randint(462, 562),randint(1, 2)])
				timer = 0
			index = 0
			for p in acpos:
				if acpos[index][2] == 1:
					acpos[index][0] += -(p[2]+4)
					acpos[index][1] += -(p[2]+4)
				elif acpos[index][2] == 2:
					acpos[index][0] += -(p[2]+2)
					acpos[index][1] += -(p[2]+2)
				index += 1
			for p in acpos:
				pygame.draw.rect(screen,(255,255,255),(p[0],p[1],p[2],p[2]))

			index = 0
			for p in acpos:
				if p[0] < 0 or p[1]<0:
					acpos.pop(index)
				index += 1

		pygame.time.delay(20)
		pygame.display.update()

最终，作者通过pyinstaller打包发布了一下
