Let JSON object accept bytes or let urlopen output strings

Title: JSON and Bytes: A Simple Solution 💡

Welcome to my tech blog! Today, we're going to tackle a common issue that Python developers face when working with JSON and bytes. 🐍

The Problem 🤔

With Python 3, requesting a JSON document from a URL is as easy as:

response = urllib.request.urlopen(request)

However, things start to get tricky when we want to directly load the response into a JSON object using json.load(). Normally, to create a JSON object, we can use a file opened in text mode:

obj = json.load(fp)

But in this case, the response object returned by urlopen is a file-like object in binary mode, which can't be directly passed to json.load().

The Workaround 🛠️

No worries! We've got a simple workaround that will help you transform the bytes file object into a string file object. 💪

str_response = response.read().decode('utf-8')
obj = json.loads(str_response)

By using response.read().decode('utf-8'), we convert the bytes returned by response.read() into a string. Then, we can use json.loads() to load the string as a JSON object.

A Better Way? 🚀

You might be wondering if there's a better solution or if you're missing any parameters for urlopen or json.load to handle the encoding automatically. Unfortunately, there isn't a direct option to handle this scenario.

The workaround we provided earlier is the most commonly used solution. While it might feel a bit clunky, it gets the job done without any major roadblocks.

Conclusion and Call-to-Action 📝

Handling JSON and bytes in Python doesn't have to be a headache! With a simple workaround, you can seamlessly transform bytes file objects into string file objects and load them as JSON. Remember, though it may feel a bit odd, it's a proven solution that many developers rely on.
