BeautifulSoup attribute problem

[zzy]

In line 16 where it says "for tr in soup.find("tbody").children:", it keeps telling me that there is no such attribute. The code in the example video works just fine. Can someone please help?

import requests
from bs4 import BeautifulSoup
import bs4

def getHtmlText(url):
    try:
        r = requests.get(url)
        r.raise_for_status()
        r.encoding = r.appearent_encoding
        return r.text
    except:
        return ""

def fillUniversList(ulist, html):
    soup = BeautifulSoup(html, "html.parser")
    for tr in soup.find("tbody").children:
        if isinstance(tr, bs4.element.Tag):
            tds = tr("td")
            ulist.append([tds[1].children.string, tds[2].string, tds[3].string, tds[4].string])
               
def printUniversList(ulist, num):
    print("{:^10}\t{:^10}\t{:10}".format("rank", "name", "location"))
    for i in range(num):
        u = ulist[i]
        print("{:^10}\t{:^10}\t{:^10}".format(u[0], u[1], u[2]))
    print("Suc" + str(num))

def main():
    url = 'https://www.shanghairanking.cn/rankings/bcur/2020'
    uinfo = []
    html = getHtmlText(url)
    fillUniversList(uinfo, html)
    printUniversList(uinfo, 20)
main()

I can not read the output, but there is an output

import requests
from bs4 import BeautifulSoup
import bs4
 
def getHtmlText(url):
    try:
        r = requests.get(url)
        r.raise_for_status()
        #r.encoding = "utf-8" # r.appearent_encoding
        if r:
            return r.content
    except:
        return ""
 
def fillUniversList(ulist, html):
    soup = BeautifulSoup(html, "html.parser")
    for tr in soup.find("tbody").children:
        if isinstance(tr, bs4.element.Tag):
            tds = tr("td")
            ulist.append([tds[1], tds[2], tds[3], tds[4]])
                
def printUniversList(ulist, num):
    tab = ("\t")
    print(f"rank{tab}name{tab}location")
    for a in ulist[:num]:
        print(f"{str(a[0])}{tab}{str(a[1])}{tab}{str(a[2])}")
    print("\nSuc" + str(num))
 
def main():
    url = 'https://www.shanghairanking.cn/rankings/bcur/2020'
    uinfo = []
    html = getHtmlText(url)
    fillUniversList(uinfo, html)
    printUniversList(uinfo, 20)
    
main()

maybe this is better

import requests
from bs4 import BeautifulSoup
 
def getHtmlText(url):
    r = requests.get(url)
    r.raise_for_status()
    if r:
        return r.content
    else:
        return ""
 
def fillUniversList(ulist, html):
    soup = BeautifulSoup(html, "html.parser")
    tables = soup.findChildren('tbody')
    my_table = tables[0]
    rows = my_table.findChildren(['th', 'tr'])
    headers = ["rank", "name", "location"]
    print('\t'.join(headers).expandtabs(20))
    for row in rows[:20]:
        mlist = []
        cells = row.findChildren('td')[:3]
        for cell in cells:
            value = cell.text.strip()
            mlist.append(value)
        print('\t'.join(mlist).expandtabs(20))
 
def main():
    url = 'https://www.shanghairanking.cn/rankings/bcur/2020'
    uinfo = []
    html = getHtmlText(url)
    fillUniversList(uinfo, html)
    
main()

Output:
rank                name                location

Thanks a lot, I must have done something wrong somewhere.
