【问题描述】:
我是编程新手,并尝试通过构建一些小型项目来学习。我有这段代码并且它正在工作,但是当它提取所有信息时,它在 csv 中正确格式化时遇到了问题。在我添加要拉出的价格后,它开始添加奇怪的空格。如果我注释掉价格并将其从 write 中删除,它可以正常工作,但我无法弄清楚为什么我在添加回来时会出现奇怪的空格。
from urllib.request import urlopen as uReq
from bs4 import BeautifulSoup as soup
my_url = "https://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=-1&IsNodeId=1&Description=graphics%20card&bop=And&PageSize=12&order=BESTMATCH"
# Opening up connection, grabbing the page
uClient = uReq(my_url)
page_html = uClient.read()
uClient.close()
#html parsing
page_soup = soup(page_html, "html.parser")
# grabs each products
containers = page_soup.findAll("div",{"class":"item-container"})
filename = "products.csv"
f = open(filename, "w")
headers = "brand, product_name, shipping\n"
f.write(headers)
for container in containers:
brand = container.div.div.a.img["title"]
title_container = container.findAll("a", {"class":"item-title"})
product_name = title_container[0].text
shipping_container = container.findAll("li", {"class":"price-ship"})
shipping = shipping_container[0].text.strip()
price_container = container.findAll("li", {"class":"price-current"})
price = price_container[0].text.strip()
print("brand: " + brand)
print("product_name: " + product_name)
print("Price: " + price)
print("shipping: " + shipping)
f.write(brand + "," + product_name.replace(",", "|") + "," + shipping + "," + price + "\n")
f.close()

您想向我们展示错误吗?

我添加了一张带有价格的 csv 图片,您可以在图片中看到由于某种原因它没有添加价格列,而是留出空间并移动信息
