First of all, I am getting this error. When I try running
pip3 install --upgrade json
in an attempt to resolve the error, python is unable to find the module.
The segment of code I am working with can be found below the error, but some further direction as for the code itself would be appreciated.
Error:
Traceback (most recent call last):
File "Chicago_cp.py", line 18, in <module>
StopWork_data = json.load(BeautifulSoup(StopWork_response.data,'lxml'))
File "/usr/lib/python3.8/json/__init__.py", line 293, in load
return loads(fp.read(),
TypeError: 'NoneType' object is not callable
Script:
#!/usr/bin/python
import json
from bs4 import BeautifulSoup
import urllib3
http = urllib3.PoolManager()
# Define Merge
def Merge(dict1, dict2):
res = {**dict1, **dict2}
return res
# Open the URL and the screen name
StopWork__url = "someJsonUrl"
Violation_url = "anotherJsonUrl"
StopWork_response = http.request('GET', StopWork__url)
StopWork_data = json.load(BeautifulSoup(StopWork_response.data,'lxml'))
Violation_response = http.request('GET', Violation_url)
Violation_data = json.load(BeautifulSoup(Violation_response.data,'lxml'))
dict3 = Merge(StopWork_data,Violation_data)
print (dict1)

Answer
json.load
expects a file object or something else with a read
method. The BeautifulSoup
object doesn’t have a method read
. You can ask it for any attribute and it will try to find a child tag with that name, i.e. a <read>
tag in this case. When it doesn’t find one it returns None
which causes the error. Here’s a demo:
import json
from bs4 import BeautifulSoup
soup = BeautifulSoup("<p>hi</p>", "html5lib")
assert soup.read is None
assert soup.blablabla is None
assert json.loads is not None
json.load(soup)
Output:
Traceback (most recent call last):
File "main.py", line 8, in <module>
json.load(soup)
File "/usr/lib/python3.8/json/__init__.py", line 293, in load
return loads(fp.read(),
TypeError: 'NoneType' object is not callable
If the URL is returning JSON then you don’t need BeautifulSoup
at all because that’s for parsing HTML and XML. Just use json.loads(response.data)
.
