Question

因此，我正在为youtube播放列表创建网络抓取工具，但我认为我遇到了一个错误，或者只是遇到了我很难理解的问题。

import os
import io
import pandas as pd
from numpy import arange
from bs4 import BeautifulSoup as soup
from urllib.request import urlopen as uReq

# ----
print("Paste the Youtube playlist's page(URL) here.")
url = input()

uClient = uReq(url)
page_html = uClient.read()
uClient.close()
page_soup = soup(page_html, "html.parser")

containers = page_soup.find("div", {"id": "content"})

# - Video Count
a = containers.findAll("td", {"class": "pl-video-title"})
b =(len(a))
total =(b)
d = 0

# Finds titles
for i in range(total):
    titles = containers.findAll("td", {"class": "pl-video-title"})
    titles_int = (int(d),(titles[d].text))
    print (titles_int)
    d += 1

# Finds links
links = containers.findAll("a")
for link in links:
    print(link.get("href"), link.text[0])

它以前是打印\ n的实际换行符，但是现在尽管没有编码属性，它仍然可以打印。我不明白为什么要这么做，因为实际上没有编码属性。我真正能弄清的是，此行titles_int = (int(d),(titles[d].text))提示了该行。

Answer 1

像这样修改您的代码：

# Finds titles
for i in range(total):
    titles = containers.findAll("td", {"class": "pl-video-title"})
    print(int(d), titles[d].text)
    d += 1

否则，您将创建一个tuple对象，并且打印元组会导致这种问题。您可以在此答案中看到原因：print tuple beautifully with newline

Python 3打印\ n而不是在Web scraper中换行
