如何在 python 3.x 中打印格式化数组？

Question

I trying to write a web-scraper for wordreference.com, the code is this:

import bs4,sys, requests
from urllib import request

def scraper():
    url=f"https://wordreference.com/iten/{sys.argv[1]}"
    r=requests.get(url)
    html=r.text
    soup=bs4.BeautifulSoup(html, "html.parser")
    x=soup.find_all("td","ToWrd")
    print(x[1].contents)

if __name__ == "__main__":
    scraper()

The code is right but the output is this: input:

python3 scraper.py cane

Output:

['dog ', <em class="tooltip POS2">n<span><i>noun</i>: Refers to person, place, thing, quality, etc.</span></em>]]

I want print only the first part of array, when is contained 'dog'. How can I resolve this problem?

Answer 1

well here is the code:

print(x[1].contents[0])

x[1].contents returns a list, so to access the string 'dog ', you need to specify index 0
