With diagnose I get 'NoneType' object is not callable error

[trynalearn]

Hi All,

Hopefully someone can help me with this.

I have this short program (I will explain the red below):

-------------------------------------------------------

from bs4 import BeautifulSoup

from bs4.diagnose import diagnose

_filehandle = open("epc_detail_page.html", "r", encoding="UTF-8")

read_text = _filehandle.read()

bs = BeautifulSoup(read_text, "html.parser")

if hasattr(bs, 'read'):

    print("has read")

print("\n\n\n")

diagnose(bs)

-------------------------------------------------------

When it runs I get this output:

-------------------------------------------------------

has read

Diagnostic running on Beautiful Soup 4.11.1

    data = data.read()
TypeError: 'NoneType' object is not callable

-------------------------------------------------------

If I look at the diagnose code it says this:

-------------------------------------------------------

if hasattr(data, 'read'):

    data = data.read()

elif data.startswith("http:") or data.startswith("https:"):

-------------------------------------------------------

So my code checks hasattr(bs, 'read') and so does diagnose, but diagnose then throws an error.

Can anyone tell my why this is?  What am I doing wrong?

Many thanks!!
