Inserte múltiples archivos JSON en MongoDB usando python

Si desea insertar datos de múltiples .json archivos, hazlo en bucle:

file_names = ['a.json', 'b.json', ...]

for file_name in file_names:
    with open(file_name) as f:
        file_data = json.load(f)  # load data from JSON to dict
        for k, v in file_data.items():  # iterate over key-value pairs
            collection.insert_one(v)  # your collection object here
