I'm getting really tired of trying to figure out why this code works in Python 2 and not in Python 3. I'm just trying to grab a page of json and then parse it. Here's the code in Python 2:
import urllib, json
response = urllib.urlopen("http://reddit.com/.json")
content = response.read()
data = json.loads(content)
I thought the equivalent code in Python 3 would be this:
import urllib.request, json
response = urllib.request.urlopen("http://reddit.com/.json")
content = response.read()
data = json.loads(content)
But it blows up in my face, because the data returned by read() is a "bytes" type. However, I cannot for the life of me get it to convert to something that json will be able to parse. I know from the headers that reddit is trying to send utf-8 back to me, but I can't seem to get the bytes to decode into utf-8:
import urllib.request, json
response = urllib.request.urlopen("http://reddit.com/.json")
content = response.read()
data = json.loads(content.decode("utf8"))
What am I doing wrong?
Edit: the problem is that I cannot get the data into a usable state; even though json loads the data, part of it is undisplayable, and I want to be able to print the data to the screen.
Second edit: The problem has more to do with print than parsing, it seems. Alex's answer provides a way for the script to work in Python 3, by setting the IO to utf8. But a question still remains: why is it that the code worked in Python 2, but not Python 3?
The code you post is presumably due to wrong cut-and-paste operations because it's clearly wrong in both versions (f.read()
fails because there's no f
barename defined).
In Py3, ur = response.decode('utf8')
works perfectly well for me, as does the following json.loads(ur)
. Maybe the wrong copys-and-pastes affected your 2-to-3 conversion attempts.
