I want to scrap the data table from the web, and there is an error occurred in for looping statement

below is my code

table_body = soup.find("tbody")
rows = []

for row in table_body.find_all("tr"):
    cols = row.find_all("td")
    rd = cols[0].text.strip()
    mv = cols[1].text.strip()
    pb = cols[2].text.strip()
    dg = cols[3].text.strip()
    wg = cols[4].text.strip()
        
    rows.append([rd, mv, pb, dg, wg])

headers = ["Release Date", "Movie", "Production Budget", "Domestic Gross", "Worldwide Gross"]

and this message error when I have tried running a code

AttributeError                            Traceback (most recent call last)
Cell In[4], line 4
      1 table_body = soup.find("tbody")
      2 rows = []
----> 4 for row in table_body.find_all("tr"):
      5     cols = row.find_all("td")
      6     rd = cols[0].text.strip()

AttributeError: 'NoneType' object has no attribute 'find_all'

what should I do? thanks in advanced
