Pandas read_html object is not callable

Question

I'm trying to screen scrape an html table located at https://www.insidearbitrage.com/insider-sales/?desk=no using the code below. I'm using Python 3.9 and it's the only version of Python installed on my pc after I previously deleted other instances such as PyCharm.

**import pandas as pd
from datetime import datetime
url = "https://www.insidearbitrage.com/insider-sales/?desk=no"
startTime = datetime.now()
df = pd.read_html(url)
print (df)**

But I get the following error message:

Traceback (most recent call last):
  File "E:/Documents/Investing/Automation/SellsInsider_Ver2.py", line 11, in <module>
    df = pd.read_html(url)

TypeError: 'NoneType' object is not callable

I can't seem to use read_html to scrape any table from any website. I have installed and re-installed Pandas as well as lxml but still get the above error. Any thoughts?

Thanks.

After much playing around, I decided to just delete Python altogether and reinstall. At one point I had multiple versions of Python on my pc including Anaconda and I had copied all site-packages from those versions into the standalone 3.9.1. Seems like things got pretty messed up so I uninstalled all python versions and re-installed and re-installed all packages which seems to have done the trick as this code now runs successfully.
