To pass a JSON file as a parameter in Python, you can use the
argparse module to define a command-line argument that takes the path to the JSON file as input.
Here’s an example of how to do this:
with open(json_file) as f:
data = json.load(f)
if __name__ == '__main__':
parser = argparse.ArgumentParser()
parser.add_argument('json_file', help='Path to JSON file')
args = parser.parse_args()
In this example, the
argparse module is used to define a command-line argument called
main function is called with the path to the JSON file as an argument, which is then opened and loaded into a Python object using the
json module. Finally, the data is printed to the console.
To run this script, you can call it from the command line with the path to the JSON file as an argument:
python my_script.py /path/to/my/json/file.json
Note that in this example, the JSON file is assumed to be in a valid JSON format. If the JSON file is not valid, an error will be raised when the
json.load() method is called.
