How to Pass a JSON File as a Parameter in Python?

Estimated read time 2 min read

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:

import argparse
import json

def main(json_file):
    with open(json_file) as f:
        data = json.load(f)
    print(data)

if __name__ == '__main__':
    parser = argparse.ArgumentParser()
    parser.add_argument('json_file', help='Path to JSON file')
    args = parser.parse_args()

    main(args.json_file)

In this example, the argparse module is used to define a command-line argument called json_file. The 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.
