How do I read a list of JSON files from file in python?

Question

I have a list of JSON files saved to disk that I would like to read. Sometimes the JSON files span more than one line and so, I think that a simple list comprehension that loops over open(file,'rb').readlines() will fail.

The files are surrounded in brackets and so passing them to json.load or json.loads won't work.

An example file would be:

[{key:value,key2:value2},{morekeys:morevalues},{evenmorekeys,evenmorevalues}]

What is the best/ most Pythonic way to read a saved list of JSON entries when the entries span more than one line?

Can you show a snippet of what your files look like? Why wouldn't they be loadable json? What added invalid formatting to them? Newlines don't matter in json. — jdi

The files begin with [ and end with ]. Answer annotated. Thanks for the suggestion. — mac389

But [] are valid json arrays. It sounds like you have an array of objects. — jdi

Your example is valid json. [] define json arrays. What you have is an array of objects:

with open("myFile.json") as f:
    objects = json.load(f)

Your code work for a single file, not a list of files

@Julien the original question asked how to read a given file that defines an array of objects. The OP only referenced having multiple files with this format. Reading more than one file is not a json problem.
