python 定时发送消息给微信好友

1、爬取爱情的文艺句子

import requestsfrom lxml import etreeimport redef save_file(love_sentences):with open('love_yaya.csv', 'a', encoding='utf-8') as f:for context in love_sentences:f.write('{}\n'.format(context))def read_url():base_url = '/article/207521_{}.html'header = {'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/87.0.4280.88 Safari/537.36'}love_sentences = []for num in range(1, 11):url = base_url.format(num)resp = requests.get(url, headers=header)text = resp.content.decode('utf-8')html = etree.HTML(text)contexts = html.xpath('//div[@class="mycontext"]/p/text()')for ctx in contexts:ctx = re.sub(r'\n', '', str(ctx))ctx = re.sub(r' ', '', ctx)ctx = re.sub(r'[0-9]+?、', '', ctx)love_sentences.append(ctx)save_file(love_sentences)if __name__ == '__main__':read_url()

2、发送给微信好友

pip3 install -i https://pypi.tuna./simple wxpy

from threading import Timerfrom wxpy import *bot = Bot()def read_file():datas = []with open('love_yaya.csv', 'r', encoding='utf-8') as lines:for line in lines:datas.append(line)return datasdef send_massage(datas, i):try:end_massage = "永远爱你的狮子"# 获取好友备注my_friend = bot.friends().search(u'小明')[0]# 发送消息my_friend.send(datas[i])my_friend.send(end_massage)# 每86400秒（1天），发送1次i = i + 1item = (datas, i)t = Timer(86400, send_massage, item)t.start()except:my_friend = bot.friends().search(u'小明')[0]my_friend.send(datas[i])my_friend.send(u"今天消息发送失败了，狮子依然永远的爱你")if __name__ == '__main__':datas = read_file()send_massage(datas, 0)

还可以用ichat包发送微信信息

3、学习知识点

python for循环

fruits = ['banana', 'apple', 'mango']for fruit in fruits: # 第二个实例print '当前水果 :', fruit

从0到9遍历for i in range(0,10):....

python 读取文件

f=open('/Users/michael/notfound.txt', 'r')f.read()f.close()

每次都这么写实在太繁琐，所以，Python引入了with语句来自动帮我们调用close()方法：

with open('/home/xbwang/Desktop/output_measures.txt','r') as f:........

一次读取全部内容到内存

with open('file.txt', 'r') as f:print(f.read())

readlines()，with方式，逐行读取

with open("file.txt") as lines:for line in lines:print(line)

readlines()，open方式，逐行读取

# 打开文件f = open("file.txt", "r")print ("文件名为: ", f.name)for line in fo.readlines():#依次读取每行 line = line.strip() #去掉每行头尾空白 print ("读取的数据为: %s" % (line))# 关闭文件fo.close()

python format 格式化函数

>>>"{} {}".format("hello", "world") # 不设置指定位置，按默认顺序'hello world'>>> "{0} {1}".format("hello", "world") # 设置指定位置'hello world'>>> "{1} {0} {1}".format("hello", "world") # 设置指定位置'world hello world'

print("网站名：{name}, 地址 {url}".format(name="菜鸟教程", url=""))# 通过字典设置参数site = {"name": "菜鸟教程", "url": ""}print("网站名：{name}, 地址 {url}".format(**site))# 通过列表索引设置参数my_list = ['菜鸟教程', '']print("网站名：{0[0]}, 地址 {0[1]}".format(my_list)) # "0" 是必须的

python 定时任务

import threadingimport timedef hello(name):print ("hello %s\n" ) % nameglobal timertimer = threading.Timer(2.0, hello, ["Hawk"])timer.start()if __name__ == "__main__":timer = threading.Timer(2.0, hello, ["Hawk"]) ##每隔两秒调用函数hellotimer.start()

注：

from threading import Timerdef send_massage(datas, i):item = (datas, i)t = Timer(86400, send_massage, item)t.start()

Timer函数传递的参数是一个pair类型
