The json.load() method (without "s" in "load") can read a file directly:
import json
with open('strings.json') as f:
d = json.load(f)
print(d)
You were using the json.loads() method, which is used for string arguments only.
The error you get with json.loads is a totally different problem. In that case, there is some invalid JSON content in that file. For that, I would recommend running the file through a JSON validator.
There are also solutions for fixing JSON like for example How do I automatically fix an invalid JSON string?.

Here is a copy of code which works fine for me,
import json
with open("test.json") as json_file:
json_data = json.load(json_file)
print(json_data)
with the data
{
"a": [1,3,"asdf",true],
"b": {
"Hello": "world"
}
}
You may want to wrap your json.load line with a try catch, because invalid JSON will cause a stacktrace error message.
Read a Windows path from a json file

How do I open or even find a json file?

I'm writing a script to automate some tasks for work, and I have it set up so that the user sets the inputs and other settings in a json file. One of the inputs is a user-specified Windows directory, and my intention is that the user will just paste it into the appropriate place in the json file. The problem is that Windows paths use the backslash character as a separator, which of course Python interprets as an escape. This causes an error just trying to read the json, so I can't even get it into my script to fix it there. In the interest of idiot-proofing the process to the extent possible, I want to avoid having the user do anything besides just paste (like change the slashes manually).
I have a workaround that uses an input prompt to get the directory from the user, but that seems clunky when all the other settings can be easily entered in the json file.
Any suggestions? Thanks.
I prefer to point pathes starting from file directory
import os
script_dir = os.path.dirname(__file__)
file_path = os.path.join(script_dir, 'relative/path/to/file.json')
with open(file_path, 'r') as fi:
pass
this allows not to care about working directory changes. And also this allows to run script from any directory using it's full path.
python script/inner/script.py
or
python script.py
I would use os.path.join method to form the complete path starting from the current directory.
Something like:
json_filepath = os.path.join('.', 'folder1', 'sub1', 'sub2', 'sub3', 'file.json')
I'm making a text based rpg in python and i learnt that the data can be saved to a json file and then can be read from it and used. But how do I access that json file? Or maybe i should do another method to save game? Also is there a way to open a json file in python so that python can read it's values?
