Python offers several different solution. json.loads(): If you have a JSON string, you can parse it by using the json.loads() method.json.loads() does not take the file path, but the file contents as a string, using fileobject.read() with json.loads() we can return the content of the file. Syntax: json.loads(jsonstring) #for Json string json.loads(fileobject.read()) #for fileobject To use this feature, we import the json package in Python script. Example 2: Python read JSON file. To write to an existing JSON file or to create a new JSON file, use the dump () method as shown: json.dump(,) # where is a Python dictionary # and is the JSON file. This dictionary is also used to access and alter data in our application So the above syntax dumps the dictionary into the JSON file . This function will convert a list of dictionaries to JSON. Example 3: Convert dict to JSON Open the json file using the open () method. There's no need to first read the file, then use loads. Method 4- using keys () method. Parse JSON - Convert from JSON to Python If you have a JSON string, you can parse it by using the json.loads() method. Using the ast.literal_eval () method : Function safer than the eval function and can be Python supports JSON through a built-in package called json. Syntax: json.dumps(dict, indent) Parameters: dictionary name of a dictionary which should be converted to JSON object. In this case they're keys, so something more appropriate would be better. output_json = json.load (open ('/tmp/output.json')) Using i and k isn't correct for this. Note: For more information, refer to Read, Write and Parse JSON using Python Pass the above JSON file as an argument to the json.load () function to convert it into a Python object. Open the JSON file in read-only mode using the open () method by passing the json file name as an argument to it. You can just use load directly. Python read json file to dictionary Introduction.
