"""
|
|
Converts a dictionary to a JSON file and saves it at a specified location.
|
|
|
|
Args:
|
|
data (dict): The data to be converted into JSON format.
|
|
filename (str): The name of the output JSON file, without the '.json' extension.
|
|
position (str, optional): The file path where the JSON file should be saved. Defaults to the directory of the caller script if not provided.
|
|
|
|
Returns:
|
|
None: The function does not return anything.
|
|
|
|
Raises:
|
|
ValueError: If 'filename' contains '.json'.
|
|
FileNotFoundError: If the specified directory does not exist.
|
|
PermissionError: If write permissions are lacking for the directory.
|
|
|
|
Example:
|
|
>>> convert_to_json({'id': [1, 2], 'value': [10, 20]}, 'output', '/path/to/save')
|
|
Saves a JSON file named 'output.json' at '/path/to/save'.
|
|
|
|
Notes:
|
|
This function automatically ensures the directory exists before attempting to write the file. If the directory does not exist, it will attempt to create it.
