用python修改json文件

我正在尝试编写一个python脚本,从json文件读取数据,对其进行一些计算,然后将输出写入一个新的json文件。但我似乎无法自动执行json读取过程。我知道这个错误。你能帮我解决这个问题吗? 非常感谢你

print([a[0]][b[1]][c[1]])
TypeError: list indices must be integers or slices, not str

with open("q.json") as datafile:
    data = json.load(datafile)

    a = ['male', 'female']
    b = ['jack', 'john', 'kay']
    c = ['id', 'telephone', 'address', 'balance']

    print([a[1]][b[1]][c[1]])
