Python error load JSON code of google API

Python error load JSON code of google API

The error arises because the data is of type bytes so you have to decode it into a string before using json.loads to turn it into a json object. So to solve the problem:

uh = urllib.request.urlopen(url)
data = uh.read()
print (Retrieved,len(data),characters)

js = json.loads(data.decode(utf-8))

Also, str(data) in the code you share will work in Python 2.x but not in Python 3.x because str() doesnt turn bytes into a string in 3.x.

Look at the error:

raise JSONDecodeError(Expecting value, s, err.value) from None

JSONDecodeError: Expecting value

Its saying I got a None when I was supposed to get something.

Check your data variable for None before calling the json.loads().

if data == None or data == :
  print(I got a null or empty string value for data in a file)
else:
  js = json.loads(str(data))

So, I had to modify your code to run. I am using Python 3.4.3 on Ubuntu 14.04.

#import urllib  
import urllib.parse
import urllib.request

I received a similar error:

[email protected]:~/src/test$ python3 help.py 
Enter location: MI
Retrieving http://maps.googleapis.com/maps/api/geocode/json?sensor=false&address=MI
Retrieved 1405 characters
Traceback (most recent call last):
  File help.py, line 18, in <module>
    js = json.loads(str(data))

    return _default_decoder.decode(s)

    obj, end = self.raw_decode(s, idx=_w(s, 0).end())

    raise ValueError(errmsg(Expecting value, s, err.value)) from None
ValueError: Expecting value: line 1 column 1 (char 0)

Basically, instead of trying to decode the valid json string, were trying to decode the Python None value, which is not valid json. Try patching in the following example code. Run it first once to double-check that the simplest json object {} will work. Then, try each different possible_json_string one by one.

#...
print (Retrieved,len(data),characters)

#possible_json_string = str(data) #original error
possible_json_string = {} #sanity check with simplest json
#possible_json_string = data #why convert to string at all?
#possible_json_string = data.decode(utf-8) #intentional conversion

print(possible_json_string)
print(possible_json_string)
js = json.loads(possible_json_string)
