Allow comments and trailing commas in JSON files using two simple Python functions to clean them up before parsing
#!/usr/bin/env python
"""
An example of how to remove comments and trailing commas from JSON before
parsing. You only need the two functions below, `remove_comments()` and
`remove_trailing_commas()` to accomplish this. This script serves as an
example of how to use them but feel free to just copy & paste them into your
own code/projects. Usage::
json_cleaner.py some_file.json
