第一周大作业：

1. 结果如下：

2. 程序源码：

```

#!/usr/bin/env python

# -*- coding: utf8 -*-

import requests

from bs4 import BeautifulSoup

def get_links_from(who_sells):

urls = []

url_base = "http://bj.58.com/pingbandiannao/{}/".format(str(who_sells))

r = requests.get(url_base)

soup = BeautifulSoup(r.text, 'lxml')

for url in soup.select('tr.zzinfo td.t  a.t '):

urls.append(url.get("href").split('?')[0])

# print(urls)

return urls

def download(who_sells):

# r = requests.get(url, proxies=proxies, headers=headers)

urly = get_links_from(who_sells)

for url1 in urly:

#print(url1)

wb_data = requests.get(url1)

soup = BeautifulSoup(wb_data.text, 'lxml')

title = soup.title.text.strip()

price = soup.select('span.price_now i')

place = soup.select('div.palce_li i')

domain = soup.select('span.crb_i a')

views = soup.select('span.look_time')

# pr)int (views

data = {

'domain': domain[0].text,

'title': title,

'price': price[0].text,

'place': place[0].text,

'views': views[0].text,

'var' : '个人' if who_sells == 0 else '公司'

}

print (data)

def main():

download(0)

# get_links_from(who_sells=1)

if __name__ == '__main__':

main()

```

3. 经验总结：方式

- 学习了用STRIP（）去除回车符号

-学习了主函数的调用次序

- 学习了中文字符串的显示
