import json

class OperationJson:
    def __init__(self,file_name=None):    
        if file_name:
            self.file_name = file_name
        else:
            self.file_name = './dataConfig/data.json'

        return data
    
    def get_value(self,id):
        return self.data[id]

if __name__ == '__main__':
    opers = OperationJson()
