Question

我试图显示我从链接中刮取的产品标题和价格，并给它们编号。到目前为止，这是我的代码。但是，我想在同一行上获得计数号和产品名称，而在另一行上获得产品价格。我该如何修改我的代码？

import requests
from bs4 import BeautifulSoup
url = 'https://scrapingclub.com/exercise/list_basic/?page=1'
response = requests.get(url)
soup = BeautifulSoup(response.text, 'lxml')
items = soup.find_all('div', class_='col-lg-4 col-md-6 mb-4')
count = 1
for i in items:
    productName = i.find('h4', class_='card-title').text
    productPrice = i.find('h5').text
    count = count + 1
    print(str(count) + '. ' + productName + 'Price: ' + productPrice)

Answer 1

问题

现在的问题是产品以java.security.auth.login.config换行符开头和结尾。

解决方案

要摆脱这一点，我们可以使用'\n'方法。另外，对于打印语句，由于产品不以换行符（strip()）结尾，因此我们需要将... + 'Price' + ...更改为... + '\nPrice' + ...。

'\n'

这看起来像是一个有趣的网络抓取项目！希望对您有帮助。

Answer 2

尝试的一种方式：

import requests
from bs4 import BeautifulSoup
url = 'https://scrapingclub.com/exercise/list_basic/?page=1'
response = requests.get(url)
soup = BeautifulSoup(response.text, 'lxml')
items = soup.find_all('div', class_='col-lg-4 col-md-6 mb-4')
count = 1
for i in items:
    productName = i.find('h4', class_='card-title').get_text(strip=True)
    productPrice = i.find('h5').get_text(strip=True)
    count = count + 1
    print(str(count) + '. ' + productName + '\nPrice: ' + productPrice)

输出：

2. Short Dress
Price: $24.99
3. Patterned Slacks
Price: $29.99
4. Short Chiffon Dress
Price: $49.99
5. Off-the-shoulder Dress
Price: $59.99
6. V-neck Top
Price: $24.99
7. Short Chiffon Dress
Price: $49.99
8. V-neck Top
Price: $24.99
9. V-neck Top
Price: $24.99
10. Short Lace Dress
Price: $59.99

Answer 3

这是您可以做的事的一个例子，以作为启发：）

import requests, json
from bs4 import BeautifulSoup

url = 'https://scrapingclub.com/exercise/list_basic/?page=1'
response = requests.get(url)
soup = BeautifulSoup(response.text, 'lxml')
items = soup.find_all('div', class_='col-lg-4 col-md-6 mb-4')

#A message that uses the array to number the items
print('the scraper found', len(items), 'items on the page')

#An empty array to append to
obj = []

#A function to make it easier to calculate with numbers
def getPrice(text):
    if text[0] == '$':
        return {'$':float(text[1:])}

#Append all the json items to the list 
for i in range(len(items)):
    obj.append(
            {
                'productName' : items[i].find('h4', class_='card-title').text.strip(),
                'productPrice' : getPrice(items[i].find('h5').text.strip()),
            }
    )

print(json.dumps(obj, indent=2))

如何在不同的行中显示python字符串？
