【问题描述】：

试图弄清楚如何使用“for”循环（或任何其他循环）来循环 url

我正在抓取 Howlongtobeat.com 的数据，网址的结构如下：

https://howlongtobeat.com/game.php?id=38050

只有“id=”结尾的数字发生变化，如何让字符串的结尾改变数字？？

page_number = range (38040, 38060)

url = 'https://howlongtobeat.com/game.php?id={page_number}'

这不起作用，因为我没有添加到字符串中

和

url = 'https://howlongtobeat.com/game.php?id=' + page_number

没有工作，因为我遇到了这个错误

 TypeError: must be str, not range

仅供参考，使用 beautifulsoup 和 csv writer 来抓取数据并将其写入 csv

我是这方面的初学者，所以从头开始

谢谢！！！！！！！

好吧 page_number 是一个范围，而不是一个整数。你必须遍历它

【解决方案1】：

from bs4 import BeautifulSoup

url = 'https://howlongtobeat.com/game.php?id='

for page in range(38040, 38060):
    new_url = url + str(page)
    print(new_url)

输出：
