You should encode str into bytes. data_string = os.environ[‘INTRINIO_USER’] + “:” + os.environ[‘INTRINIO_PASSWORD’] data_bytes = data_string.encode(“utf-8”) base64.b64encode(data_bytes)
The ordering comparison operators are stricter about types in Python 3, as described here: The ordering comparison operators (<, <=, >=, >) raise a TypeError exception when the operands don’t have a meaningful natural ordering. Python 2 sorts None before any string (even empty string): >>> None < None False >>> None < “abc” True … Read more
Here’s the general plan for Twisted. I was originally going to blog this, but then I thought: why blog about it when I could get points for it? Wait until somebody cares. Right now, nobody has Python 3. We’re not going to spend a bunch of effort until at least one actual user has come … Read more
You can safely ignore this “extra precautions” warning: your code will work the same even without list in both versions of Python. It would run differently if you needed a list (but this is not the case): in fact, features.items() is a list in Python 2, but a view in Python 3. They work the same when … Read more
Install the following module which adds the 2to3 command directly to entry_points. pip install 2to3 As it is written on 2to3 docs, to translate an entire project from one directory tree to another, use: 2to3 –output-dir=python3-version/mycode -W -n python2-version/mycode
You’ll have to tell pickle.load() how to convert Python bytestring data to Python 3 strings, or you can tell pickle to leave them as bytes. The default is to try and decode all string data as ASCII, and that decoding fails. See the pickle.load() documentation: Optional keyword arguments are fix_imports, encoding and errors, which are … Read more
