How to print integers as hex strings using json.dumps() in Python

Question

Currently I am using the following code to print a large data structure

print(json.dumps(data, indent=4))

I would like to see all the integ

Answer 1

One-liner

If you don't mind your hex strings quoted, use this one-liner:

print(json.dumps(eval(str(json.loads(json.dumps(data), parse_int=lambda i:hex(int(i))))), indent=4))

Output (using Gerrat's data again):

{
    "test": "0x21", 
    "this": "0x63", 
    "something bigger": [
        "0x1", 
        "0x2", 
        "0x3", 
        {
            "a": "0x2c"
        }
    ]
}

This is a better answer than my previous post as I've dealt with getting a pretty-printed result.
